That's a very good point on not buying on looks alone.
I built my car and the main intent was a road-eating, very good handling, lot'sa power roadster-like thing, so I mostly concentrated on getting the suspension just the way I liked it, an engine with plenty of power and a transmission geared for twisty New England roads. The car was originally black gel coat with burgundy interior and I was OK with that color combo.
Several years went by and I was still working on the build and not yet on the road (I know - Finding quality build-time was hard back then) but then I saw a co-worker's pearl white Audi and fell in love with the color. The bonus was, the interior looked a lot better against white than the original black. A friend had my original black color combo and it just doesn't "pop" like the white/burgundy does. A Hot Rod friend sprayed the new color and you really can't tell that the car was anything other than white, anywhere. I made sure it had a plastic film on the nose because any stone chip would pop the paint off and show black underneath. 
It's the same old car underneath, with the exception of going to a 3:88 final drive to get the revs down a bit on Interstates, but all anyone on here has seen is the white version and it still draws lots of attention.
