I do not want to buy a coach that is not local, I want to be able to see and feel the bus before I buy it.
I just took a quick look on Ebay and saw a fully converted MCI 9 with a buy it now of 13,000. There are definitely good deals out there. You can also use Crazedlist.org and search Craigslist by region or individual markets.
My $.02 is to find the best you can like the experts have said. My bus was $29,000, then $4700 for new clutch and power steering pump, blown air bag at rv park, decided to have all 8 replaced and power steering box leak repaired another $4400, 6 new back tires $1900. So like they say after you get it home other things can pop up that need doing. I am mechanical but theses were items that I was not able to do at home so I had to pay for them.
