Audi RS4.
I like German muscle more.
Faster, more luxurious, handles better.
If you are talking about America muscle only, I prefer the Pontiac G8 GT.

e92 BMW M3=Best muscle car to date.
If you are referring to american cars, i’d have to say…none… I can’t think of a single american muscle car I’d actually want to drive other than the Dodge Viper ACR, that is one mean car. Corvettes are great no doubt, but they’re everywhere, part of owning a cool car is the rarity factor, and there is none when talking about the Vette. The mustangs are horribly outdated, and suffer from a complete lack of handling. The Chargers are stupid looking, and don’t even come with a manual gearbox, therefore rendering it as a “sports car wannabe”. The challenger…that may be the best of the three options you provided. Dodge actually put some race technology into this car, and it handles well. There is more to cars than straight line performance. Check out the BMW, if that isn’t muscle enough for you, I don’t know what is!

Pontiac’s G8 GXP is a world-class performer, and handsome to boot.

Ford GT. Not the Mustang GT, just the GT. It’s out of production now but for two years it was the domestic muscle car to put all others to shame.

go for a mustang GT.

Or, if money isn’t a factor, try a new shelby gt500.

go to ford.com

ford mustang = pos has technology from the 1800′s (live axles omg)
charger = ugly
challenger= best of the 3
