Even a decent paint job by a quality paint shop is going to be reasonable compared to a new car... but, yeah, a wrap is probably the right option. Go with something tacky! :D
Six years old, I'd just take the cash and own it. "Yeah, damned tanker of road tar blew up in front of us. Covered the car in tar, it was worse than Lightning McQueen and Bessie! Anyway, insurance paid for it, so... paid the car off and I made money. I don't have to see it while driving it, and I'm not worried about anyone stealing it!"
Also, local teenagers and some clay bar go a long, long way.
