9. 1929 SSK Roadster – $3.3 Million

The SSK was a two seat sports car produced from the late 20s up until the early 30s. This model is the first of two on our list. The SSK was one of the most successful racing cars of its day and is very scarce now, with experts estimating that there are only about five left at the very most. This one sold in Paris for just over $3.3 million back in 2004. This vehicle, with its 200+ horsepower straight six engine and impressive racing record, is considered one of the best cars of the 20th century.
