#4. Mercedes E Class – Sold 50000+ Cars
While this is only the fourth best selling luxury car, it’s one of the best for the mid-tier luxury market. The E-Class sits about $15000 to $20000 higher than any other car on this list, and there’s a reason. Mercedes-Benz knows how to do luxury cars right. BMW may be more fun to drive and Audi may be more practical, but when it comes to German Luxury, Mercedes is still the preferred option.
