So herein lies the great paradox of used car buying: do you spend high and buy something newer and with fewer miles, or do you spend lower and use the difference to make it your own? I've been on both sides with the VX, as I bought my first one with 22K miles on it 4 years ago for $14K. Got a good amount of mods done on it before a drunk driver totaled it last fall, but most were just cosmetic in nature. When I went hunting again last fall I actually had more cash in hand than the first go-round due to the insurance pay-out, but I decided to buy a cheaper VX with more miles and use the money to do more serious mods (5-speed transmission swap so far, and at least one more this spring).
It probably will be hard to find a 2001 VX with 90K miles (regardless of color) for $7K or less unless it's on the rough side. On the other hand you're far more likely to find a 99 with a new engine or transmission (as you already have) for the same price. If you can live with 16" wheels (until you replace them), no automatic climate control, and a monotone color (silver, black, and white were your only options in 99) the latter may be the way to go.
