Kaufberatung SLK R171

Hello everyone.. Would you like to hear your opinion about this car. http://www.autoscout24.de/Details.aspx?id=bjtrcxcnq3pj I also looked at the car on Saturday and tried it, the car is really very good and drives well. Unfortunately I don’t know so much about used car purchase. The dealer seemed quite serious to me. But the car is sold in the customer order. Used car guarantee I could get at that price. Can repairs come in the next time? How long do you drive such a car in NORMALFALL? If something was wrong with the car, would it show me in the board computer or? Tires and brakes were quite new. So if you ask me just write… thank you in advance….
