425 HP

Did we save the best for last? That depends on how you feel about Chrysler’s big muscle sedan. We did save the most powerful car for the end, however, with its 6.1-liter Hemi V8 exceeding not just 300 hp, but going well beyond the 400-hp mark as well. 2006 was the second year for the model, and though it’s among the oldest on the list, NADA reports average prices for a 425-hp 300C SRT8 with 100,000 miles fall just below $10,000.
