I thought i was exempt from scraping with two weeks of luck, but scraped over a speed bump (not even a big one) and I was going slow. Watch yourself past -2.0.
Depends do you know what the codes stand for? If it's just in need of new spark plugs and a timing belt and maybe some cleaning of the gaskets (not easy, but what my check engine light was on for my v6 2k1[which took a local shop only one night to do]) then I think it's well worth it. I guess...
