We've seen many levels of Project Car Hell since the Sprite-versus-Fiat matchup that started it all. Some PCH contestants have proven more compelling- if that's the word- than others.

We've been doing this long enough that it's time for a Greatest Hits episode (though we haven't reached the point of the PCH reunion tour- that comes later), so we've gone through and found the Project Car Hell episodes with the largest amount of viewer traffic. You've voted with your eyeballs, and it's interesting to see what attracts the largest number of optics. It turns out that BMWs and Ferraris tend to be the most popular, with nutso engine swaps also generating plenty of discussion. Here you go: the Top 30 Fieriest Project Car Infernos. Be sure to crank up the Project Car Hell Song while reading!
