I would suggest trying to get one with as straight a body and paint as possible. Body work tends to be really pricely even when compared to engine work, electrical, AC, etc.
As an example, in SoCal to paint a VX that has a number of door dings at a respectable autobody shop is typically around $2.5K!! A little labor could be saved if you remove all of the lights, door locks, etc. yourself.
On a side note - Even if you don't like white cars, white tends to hold up the best over the long haul.
