Please provide information on the rust on the underside. It seems to be a matter of chance or inconsistency, where some individuals will be satisfactory while others will not. A few years ago, my previous SLK had same issue, and Mercedes-Benz would not acknowledge it, despite the fact that I had been using their services exclusively since the car was brand new. Other individuals were fortunate in having their Mercedes vehicles replaced.
I have discovered a device for emitting soot and have spoken with the proprietor. It is likely that I will proceed with the purchase. The car is equipped with memory seats, has a reasonable mileage, and comes with a well-documented maintenance record. I have examined the Euro 6 facelift 350 models, but the availability of memory seats, mileage, and pricing is limited and uncommon.
