Viper over Mustang.
If your going to buy a big fat heavy over powered lump of steel then do it porperly. The Viper is heavier, more powerful, faster and oh soooooooooo much coooler!
Trucks? who cares.
Trucks are for carring large loads not racing.
Neon vs Focus?
Focus all the way! Its a British designed car, with a great agile chassis, lots of power, and lots of charm.
The Neon will always be a Neon, no matter what you do to it.
....oh, and the Focus is driven by that Collin McRae fella, when was the last time you saw a WRC Neon.
