Hi, I have the possibility – through a friend – to get a SLK relatively cheap – about 600€. The SLK R171 BJ 2004 has approx. 110.000km, automatic, was driven only by an older lady, only long distance and is completely checkbook maintained. I have driven it myself already several times and I really like it very much. Only the sports seats, at least on the driver’s side, I find something uncomfortable (but good hold!). Otherwise it is really super fun in the curves, performance fin I don’t really notice anything noticeable when driving, but I don’t know how to do it so well either. Everything is a little bit tricky, but no more than other convertibles and fully within the frame. However, I noticed that the window lifter works on the driver’s side without any problems, but when driving up, the door shakes something. What could that be? My question is now before I buy it, what I should pay attention to. Is there anything that I need to do? How durable are such cars? 110,000 seem a lot to me at first, but are not so much for the car, at least according to what I read.
