That's precisely why I asked the question here, where hopefully somebody could shed some light on something that I might have to watch out for. After looking at the exclusions in the MaxCare warranty, I can't find anything that would be catastrophic, or that I couldn't do myself (fluids, brakes, hoses, etc).

Assuming the car hasn't been wrecked, what potential items could be "wrong" that might not be covered under a warranty?
