Hi, Hello everyone, the old driver of the car inspector has met you again. Welcome to this issue of used car inspection fun. I am an omnipotent and eye-catching master, not just a used car inspection technician who has repaired cars. , is also an accident car dissuade teacher, helping customers solve all difficulties is my value~
I work in the automotive industry, and often have friends around me who ask Dana about buying a car. I received my cousin last night. I asked you what car to buy with a budget of 200,000? Dana's first thought should be those familiar names, Magotan, Accord, Camry, and Tiguan L and CRV in SUVs, but as a young man born in 1995, his cousin obviously wants a car with more personality and good looks. , Dana blurted out: 09 BMW 740.
It's not a big deal, because I just tested a car like this last week. You know, a 12-year-old used car can be bought for less than 200,000 yuan. Some friends may have a few question marks, why should I buy this car? Does it burn oil? Can you afford it? Do you run a repair shop at home? Dana can understand the puzzled feelings of friends, but what kind of car to buy really depends on personal needs. Only the person who uses the car knows whether it is suitable or not.
For example, a classmate's mother bought a Mercedes-Benz GLB. In Dana's eyes, the GLB is a car to fool people, but when it comes to the car needs of the classmate's mother, they are in business and mainly in the township market. So face first. What are you talking about, whether the power is good or not, whether the interior materials are good, whether the third row can sit people, these people don't care at all, what kind of power do aunts in their fifties play with you, they just want their cars With the standard and the big shell, going out to run the market shows that I have strength.
As for this twelve-year-old 740, Dana has no idea why customers bought it. Although he is curious, it is not Dana's job to inquire into customers' inner thoughts. condition of the car.
Model year: BMW series 2009 740Li luxury model Second-hand cars of this year must have bumps and scratches on the appearance, so don't think about the original paint. The customer's requirements for appearance are not high, and he said that he plans to do a full car paint after buying it back. Therefore, the exterior paint surface is briefly reviewed to see if the main frame is damaged.
However, it felt bad as soon as it came up. The thickness of the paint surface of the cover was abnormal, not too high, but too low, far below the normal value! Friends who often read our posts should know that the outside repair shop and 4S shop have one less process for painting than the original, and the thickness of the paint surface does not meet the original technology standard, so the cover is suspected of being replaced.
I quickly read all the paint surfaces. Except for the roof, almost all the rest have been repainted. Fortunately, there is no problem with the frame. The ABC pillars on both sides and the upper and lower side beams have not been repaired by sheet metal cutting. There are many minor injuries, but no major injuries.
Looking at the whole car glass, BMW's front windshield has no date, but the inner glue line is not so neat, and there is a phenomenon of overflowing glue, which can only happen after manual glue, so the front windshield is replaced later. I think that the front cover has been replaced, so is this glass broken in the same accident? Write it down first, and continue to look for clues.
When the hood is lifted, the engine compartment is normally dusted, and no exaggerated panel wax is used, so the original state is convenient for us to detect. This 740 uses an inline 6-cylinder 3.0T twin-turbocharged engine code-named N54B30A, with a maximum power of 240KW, a maximum horsepower of 326 horsepower, and a maximum torque of 450 Nm. It is matched with a 6AT gearbox and can break 100 in 6 seconds. The power is strong enough, and the fuel consumption of this engine is good, it is not particularly expensive, and the maintenance is not very expensive. I mean: it is cheaper than the Mercedes-Benz S-Class.
As Dana expected, there was an accident at the front of the car. When checking the fixing screws of the hood and the fender, I found traces of disassembly. The lock nose of the hood was also removed. The lock nose will not be moved by general painting or adjusting the clearance. Combined with the inspection results of the appearance, the hood is 100% replaced.
The accessories at the front also need to be replaced. First, the two headlights and the headlight frame are disassembled. If there is an accident ahead, the headlights are generally unretainable.
The front anti-collision beam screws are removed, and most of them are replaced later.
Then the water tank frame is disassembled and the water tank replaced. The rhythm of the front mouth set!
Looking down, I saw that the two longitudinal beams have no signs of bending, deformation and folds. No problem, it means that the accident ahead is not particularly serious. The longitudinal beam has withstood the impact and is not damaged.
The accident investigation is over, let's look at the engine condition. Oil leakage in the valve chamber is expected, and the removal of the valve cover is also expected, and dismantling it is to repair the oil leakage. There is no way, this common problem of BMW is difficult to cure for a long time!
The place where the oil leaks is not only the valve chamber, but the turbocharger also has obvious oil leakage.
The position of the timing side cover is stained with oil.
There are also oil stains next to the radiator fan.
The oil stain on the oil filler also makes people feel unsightly. The condition of the engine is less than ideal, and there are some parts that need to be viewed from the chassis.
There is still a problem in the engine compartment, that is, all electrical connectors are aging and brittle. This situation still needs to be paid attention to in time to avoid problems later.
came to the car, the central control design 12 years ago now looks a bit shabby, but many of its configurations and functions are still outdated today. After so many years of oxidation and wear, the steering wheel, gear lever and seat have been left with the marks of the years, it just doesn't look so obvious from the photos.
The wear and tear of the main driver's door trim panel is not a concern. If you mind, it can be refurbished later.
The interior is clean, the brakes and accelerator pedals are dust-free, and wear is not noticeable.
The whole car seat screws are not removed, the bottom frame slide rail is not rusted, and there is no sediment residue in the gap. Only the main driver's seat has a slight slump and folds.
The seat belt has not been disassembled, and the manufacturing date is in line with the time of the original car, indicating that the front accident did not cause the seat belt to be locked and replaced. The interior of the seat belt socket is also very clean, and there is no sediment and rust.
When I disassembled the dashboard, I was shocked to see the metal skeleton. The upper part was a little rusted, but after careful inspection, it was judged that it was a phenomenon of oxidation and anti-rust over time, not the kind of rust caused by blisters.
then read the OBD data of the vehicle and the mileage of the gearbox, and the computer reported the fault code of the electronic accessories, which is irrelevant for normal driving; the gearbox data is consistent with the odometer, which ruled out the suspicion of the vehicle's meter adjustment.
After reading the interior, I drove the car to the road for a road test. Dana did not brag about its strong power and driving control, but focused on the engine and gearbox conditions. Simply speaking, the road test experience shows that there is nothing unusual about the running of the vehicle, but the resonance problem can be clearly felt when waiting for the traffic light, and the instrument panel is also accompanied by the same abnormal sound.
I went to check the chassis on the way. After the car was lifted, I could see a large amount of oil leakage at a glance. When I checked the engine compartment, I knew that the problem of the chassis was inevitable. Is it still called BMW if it does not leak oil? What's more, it's still an old BMW for so many years!
There is also an eye-catching place, a scratched guard plate sagging! This has to be maintained and replaced. After all, such a luxurious D-class car, the image of the guard plate dragging on the ground is too cheap.
Let's take a closer look at the places where the oil leaks from the chassis. First of all, the oil leakage at the junction of the engine and gearbox is serious, and the specific source of the oil leakage cannot be seen. However, the screws at the junction of the hair change can be seen vaguely with disassembly marks.
The oil leakage of the engine oil pan is expected, most of which are caused by the wear and aging of the oil seal after the curve, and the sealing is not strict, and needs to be repaired later.
The lower part of the gearbox casing is covered with oil stains, is there any oil leakage into a river?
The transmission radiating oil pipe seeped oil. Fortunately, the maintenance here is simple, just need to replace the oil pipe, it is not like repairing the oil seal after bending.
The oil seepage of the gearbox valve body cover is slight compared to other places.
The gearbox oil pan screw is disassembled, it seems that the gearbox has been disassembled and repaired.
There is also an oil leak, the bottom of the steering machine.
After reading the chassis, Dana was speechless. There must be leakage wherever he could see. If the engine compartment inspection was added, there would be more than ten places where the whole car leaked oil! If it is all repaired, the cost of 20,000 may not be able to hold, plus the whole car painting and other parts of the maintenance, the maintenance cost of 30,000 is appropriate.
Briefly summarize the test results, front accident, interior wear and tear, and multiple oil leaks throughout the car. After starting, it needs to be overhauled. Tell the customer that the customer has been contemplating for five seconds, which is time-consuming and laborious to repair, and cannot be served! So decided to give up.
This 740 had a manufacturer’s guide price of 1.378 million back then, a veritable million-dollar luxury car. Today, the price of a second-hand car in normal condition is around 180,000 to 90,000. It has depreciated by 1.2 million in 12 years. What is the concept? A suite in a third-tier city. However, we cannot look at the gains and losses of the original car owner purely from the numbers. In the past twelve years, the value of this car to the original car owner may have far exceeded ten suites. Therefore, although the depreciation amount of a luxury car is high, the original The owner is not necessarily at a loss.
The price of this 740 is 178,000. In the normal market range, combined with the condition of the car, it is not worth starting. With 178,000 yuan, you can buy a million-dollar D-class luxury car, which seems to be a bargain, but in fact, the cost of maintaining a car in the later period is not a small amount. If the car is in poor condition, it will not only make you worry about repairing the car every day in the later period, but also make you pay double the balance on your bank card. In this way, you will not enjoy the sense of superiority brought by a million-dollar luxury car at all, but will let you experience the taste that you can't afford to repair. Therefore, if you want to buy a second-hand luxury car, it is necessary to find a friend who understands cars to help you check the condition of the car, and then start after knowing the most real car condition to avoid getting into the pit.
Okay, that's it for today's inspection and sharing. I'm a used car inspection technician of the car inspector.Like it if you like it, spray if you don't. I repair a lot of cars, read little, and write poorly. Please bear with me. Car inspector, willing to be your best friend who knows cars!
