Hello everyone! The old driver of the car inspection family met with you again! I am Xiao Xiaodong, the most low-key inspector in the car inspection family. Everyone in the car inspection family calls me Xiaobao. Mainly my tall '1.58' tall guy. The best thing is to look at the chassis without a lift. My brothers are all jealous, but I can't be proud. Although I am small, I am a treasure! The detection technology is also very cool~
As a D-class executive sedan under Mercedes-Benz, Mercedes-Benz S-class can be said to be a king-like existence. Over the years, the status of the first brother of luxury cars has never been shaken. After all, it brings The aura and sense of identity it gives are unmatched by other cars. In a sense, owning a Mercedes-Benz S-Class is not only a tangible tangible asset, but also derived intangible commercial value and wealth value, which has always been sought after by business people.
And smart businessmen often like second-hand Mercedes-Benz S-Class, because used car is cost-effective, and it can support the row without too much cost, especially the low-end models are particularly popular, a little older but still in good condition The line is also optional, and not every boss who gets in the car will ask you if it is a used car, nor will you go to the engine compartment to see what engine displacement it is. So, today is another story about a boss who wants to choose a second-hand Daben, but his luck doesn't seem to be very good.
This is a 2008 Mercedes-Benz S350. Although it is a little old, it still has enough aura. It can be cleaned up after cleaning. The brother who bought the car was smiling at the beginning and had a good talk with the owner of the car dealership, but he fell into a depressed mood after learning the final test result. What happened to this car? Listen to Xiaobao come one by one.
Model year: 2008 S 350 L luxury
Factory time: 2008-05
Display mileage: 251046KM
Manufacturer's guide: 1.398 million
Seller's quotation: 176,000 The significance of the paint surface is not only to see whether it is the original factory, but also to judge whether the car has been repaired by sheet metal from the paint surface, and then to judge whether the car has a major accident. The paint surface is a very important reference, so we say This step is essential.
It took half an hour to inspect the paint surface. Except for the roof and the ABC pillars on both sides, the other surfaces have sheet metal spray paint . The on the exterior scratches the more. After all, it has been open for thirteen years. Moreover, after changing four owners, each owner has a different driving style, and there will definitely be some bumps. Fortunately, there is no body cutting and welding.
The engine compartment is full of dust. Although it doesn't look good, inside is a serious 3.5L V6 large self-priming, front-rear-drive layout, which can burst out a maximum of 272 horsepower and 350 cattle The energy of the meter is matched with a 7-speed manual gearbox, but there are many years, and we need to further test the specific working conditions.
First, let’s investigate a wave of front accidents. Although the front water tank frame and front anti-collision beam have been disassembled and assembled, they have not been replaced, and they are still original parts; the two longitudinal beams and the frame are not damaged; the front bumper and two large The lights have been replaced, and the two headlights have been modified with new ones, which is not a big problem.
Looking at the engine part, the valve cover screw has been removed, and there are traces glued on the back; continue to check that the intake manifold, exhaust manifold and timing side cover have also been moved, at this time Xiaobao felt a little bad in his heart. It is estimated that this engine has broken down and repaired .But it's not completely sure yet. I'll take a look at the feet and ingot beams when I check the chassis for a while.
Here to popularize the Mercedes-Benz M272 engine is actually a common problem, that is, the camshaft is prone to failure, and the camshaft will make a sound of iron when stepping on the accelerator after a problem, and the official chain will be pulled after a long time. If it is long, and then there is no oil, it may also be placed on the road. Xiaobao started it and tried it. There is no problem for the time being. Now it is the bad engine overhauling .
For the oil, the oil should be changed, the color is dark and there are impurities; the water content of the brake oil exceeds the standard and needs to be maintained and replaced; the battery and antifreeze are in good condition.
Next, check the cockpit. The interior design is an old-fashioned style, not as smart and eye-catching as the new model. The of the seats and dashboard is more seriously worn, and the interior color scheme is old and old, of course. Looks luxurious when new.
Observe that the fixing screws at the bottom of the seat have traces of turning and disassembly, but there is no sign of soaking in water. The condition of the seat is indeed relatively poor, and there are small damages in the corners. After reading the meter, it is 250,000 kilometers, which is understandable.
The instrument panel screws have not been moved, and the main driver's airbag and seat belt are all original, which means that the possibility of serious accidents ahead is very small, but the wear and tear is indeed a bit large.
Then I tested the function buttons of the whole car. Most of the functions such as seat heating and ventilation can work normally, and the pneumatic shock absorption can also be raised and lowered normally. However, the electric sunroof has malfunctioned, the reversing image is not displayed, and the front fog lights are not Liang, the customer's eldest brother said that the seller promised to repair it for him, Xiaobao thought that the cost of repairing the central control is not cheap!
The transmission data stream read through the OBD computer is almost the same as the meter display kilometers. The use of the interior is also in line with the state of 250,000 kilometers, and there is no meter adjustment.
Take the car to a nearby repair shop to check the chassis, and then you can confirm whether the engine has been overhauled. Remove the lower guard plate of the engine, and see that the fixing screws of the engine feet have signs of disassembly and twisting. The basic function of the engine feet is to fix the engine gearbox on the frame. The movement of the engine feet does not mean that the engine is overhauled, but the engine overhaul must be The feet will be removed.
The key engine and gearbox connecting screws also have disassembly and assembly marks. The front subframe screws have also been removed, and the gearbox foot fixing screws have not been spared. The above findings are in line with all the characteristics of an engine overhaul, so the answer to this question is: Yes. And there are a lot of oil leaks. The seller quickly said that the engine was repaired because burned oil . 250,000 kilometers to repair the engine is also normal, after all, German cars have problems that burn oil.
The steering gear and the two front wheel shock absorbers have been disassembled, and the chassis can be disassembled in a large area! In the end, Xiaobao also found traces of exhaust pipe modification. Generally, this kind of Mercedes-Benz modification is normal, just like my C63, it feels boring not to modify it! Although many parts are disassembled, the chassis is still very stable.
(the applet has been added here, please go to the Toutiao client to view)
finished the inspection after reading the chassis, sort out the car condition: the skeleton structure of the whole car is intact, there is no major accident and no blisters, the main problem is that Engine hoisting, dismantling and repairing and the aging and wear of the vehicle. In the later period, with the increase of the age and the accumulation of normal use, there will inevitably be failures and maintenance of wearing parts, and the cost of parts and labor hours of Mercedes-Benz is relatively high, although it is A 13-year-old car is still a million-level standard!
Explain the situation to the client brother clearly, the brother asked me what is the disadvantage of overhauling the engine? Since eldest brother asked, Xiaobao, I will add some knowledge to you. Generally, engine overhauls are done on the one hand, and there are two situations in the result of the maintenance. One is that the engine is much better after the repair; the second The reason is that there will be many small problems after major repairs, such as oil leakage and the like. This has something to do with the level of the mechanic master, and the repair of the high level is much better. Brother
asked me about the cost of maintenance in the later stage. I made an estimate, about 10,000! If there are a lot of faults later, the cost of repairs will only be higher. It seems that the client brother still doesn't understand, but he doesn't know how to ask questions. After all, he is not too professional, so he can't immediately decide whether to buy or not. Xiaobao suggested that he should consider and consider according to his own situation.
The new S350 cost almost 1.5 million when it landed. The current market for used cars in normal conditions is around 180,000. However, there is no unified pricing standard for used cars. One price per car is important. Today, this car is cheaper and only costs 17 Ten thousand. However, Xiaobao reminds friends that 170,000 seems to be cheap to buy a Daben of this level, 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, you will not be able to enjoy the benefit value brought by the million-dollar luxury car in the later stage, but it will make you experience the bitter 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 knows cars to help you check the condition of the car. After knowing the most real car condition, you can decide whether to buy it or not 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.
