Hi there, so far I have always purchased my vehicles by leasing. Since I have recently had to drive about 30,000km per year, I would like to buy a used C-Class for the first time. My goal is to buy a limousine or a station wagon. Since I have not yet bought a car, I have opened up two questions:1. Financing: Due to the high driving requirements, I am not sure how to make the financing here best. r that I should choose a financing with down payment and closing rate (Plus3 financing), because I can then return the vehicle to the dealer after 4 years of use (and a mileage of probably 120,000km (+kilometre level of the previous owner) for example. I would have the certainty that I would have a buyer for the vehicle despite increased mileage. The next point is that I would like to buy a diesel car, but I live in a city where There may be driving bans (even if I can’t imagine it with regard to new diesel vehicles >6). So I would have the safety here too that I would have a customer for the vehicle in an emergency. Or what would you recommend me? 2. Duration of ownership: I am also unsure about the holding time of the vehicle. Due to the high driving performance I had planned to keep the vehicle 4-5 years. Of course, vehicles are often much more durable, but you can choose between nn also does not rule out that with a mileage of approx.150,000km and more, the first major repairs can happen. Or am I wrong here? Should I aim for a higher stopping time in spite of the many kilometers per year? Thank you in advance for your tips!
