12 of the most expensive Mercedes-Benz cars ever sold – You need to see #1 (With Pictures)

5. 1929 38/250 SSK – $7.4 Million

This car is a slightly different variant on our number eight and was sold by British auction house Bonhams, over 10 years ago, back in 2004. As I previously noted, the car was an engineering phenomenon at the time, and was very successful in racing at the time, so we can understand why it was so unique. With so few left over, it is no wonder that these cars sell for so much at auction, and will likely continue to do so.
