My list isn't nearly as long as everyone elses, but I guess me being 23 years old, you all have a head start. But my most recent two are pretty impressive, IMO!

In chronological order of purchase:

1995 Ford Escort (sold 2 months after I bought it). Complete with blue confetti interior and dash, non-working radio and A/C, and those seatbelts that strangle you when you open the door.

2005 Toyota Corolla S (sold 1/2008). Fully loaded with classy 18" chrome wheels, tint and amazing aftermarket sound system.

2001 Z51 Corvette Convertible (still have...forever). Too many mods to list.

2005 Crossfire Ltd. Roadster (still have...forever). Need I say more?

Short, but sweet.
