Carfax certainly won't show you everything but, when spending so much money on a coach, SOME info is way better than no info. When we were shopping for our coach, we signed up for unlimited carfax inquiries for a month then went looking around the country for what we wanted. I pulled a carfax on every coach that was interesting. Most (if not all) had DMV records that showed number of owners and registration states. Some showed service records, very few showed wreck repairs. All of this info is useful.
