I collect errors but squished up or mis-aligned tampos don't appeal to me as mostly they jus t don't look good. On rare occasions, a mis-aligned tampo might create a unique look that's appealing - but those are preety rare occurences. I am more apt to collect missing tampos, whether it's one color or an entire side or top of the car. Often time a tampo missing from the entire top/side of a car will actually improve its looks.

If you like how your error car looks, keep it. It's always a good conversation starter anyway. If you don't like it, trade it for something you like. "Collect what you like."
