Cracked windshield repair, leather and vinyl repair, stinky car odor removal, chipped paint on bumpers and so on. Easily get side-tracked by thinking about additional services even though they might be needed...

Stick to the original idea but adding doorhandles to brighten them up should be good enough.

As far as finding locations to do this biz, here in sunny California there is always a fair, swapmeet, antique show or what have you as an outdoor event, attracting 1000's of visitors. Contacting the promoters of the show and asking for a couple of spaces in the parking lot, could that be doable?

Just thinking...
