Mercedes or US Car

Hello I am looking for a car in the price range from approx. 10,000€ to 12.00€. It should be a limousine, a coupe or a convertible with a fixed roof. The car should be either a Mercedes or an American car. Although many advise me from a Mercedes, because I am still relatively young and Mercedes is still called a “rentner car” in some people. The year of construction should definitely be after 1995. The mileage must not be over 120,000Km. Cars I would have liked for example: – Mercedes SLK (R170/R171) – Chrysler Crossfire Coupe (is technically also a SLK) – Ford Mustang (5. Gen) – Mercedes E-Class (W211) – Mercedes C-Class (W204) – Mercedes CLK (C208/209) My questions are now whether you can recommend or advise one of the vehicles I have mentioned. Also interesting is which of these vehicles is the cheapest in the maintenance. If you think of other cars, I would be happy if you could call them to me. Thanks already in advance!
