This is a big plus for a lot of people. By trading in your car and buying a newer used car, you can afford to get a vehicle that you could not afford new. You stretch your car-buying dollar and can afford a two or three-year-old luxury car that fits your budget.
Also keep in mind that luxury cars are the first to be packed with more quality materials and the latest technology. We're talking everything from rich leather heated seats, to the newest infotainment and driver assist features. Those tech features will still be fairly current for the next five years. You can drive a slightly used BMW on a new Ford budget.
