My dream cars are the Lotus Elise (Pure black with black tinted windows, maybe some white tribals if I've got real money to burn; The Esprit is faster, but I don't like the blocky front.) and the Chrysler 300C (Black with a thick white stripe over the driver's side, extremely thin light blue stripe right next to it, blue slow flash neon and blue tinted windows. I love this car, and you don't need much vinyl to make it badass.).
Yes, I play too much Midnight Club. At least I don't have pics. (Actually, I may try to get some...)
A car I love and might actually get would be the Ford Crown Victoria, the old one that used to be used as a police car (I think it's the LTD edition). The things are tanks and have a huge trunk.
If I can expand it to "vehicles in general," I'd like an M1A1 Abrahms Main Battle Tank. I'd probably modify the turret to fire something cheaper than a shell (like pop cans! On that topic, does anyone know what that movie is? Some chick has a tank that's intelligent or something and fires pop cans. I can't remember what it's called, and it's really bothering me.) and use all my money to mount some .50 caliber machine guns on the sides that would be manned from outside. And then buy ammo for them. Where's my welding torch?
