Thanks for your replies guys. Yes, I've been cooling off on this bus, especially when I found out the mileage is 232K. Even if the drivetrain was rebuilt, that's getting a little high in terms of overall miles on the chassis, especially considering that his best price is $3,750. I see buses go at auction all the time for $2,500 with under 150K.
I would have to drive at least 3 hours to look at the bus in person, so unless I'm 95% sure I'm going to buy it, I'm just not going to deal with it. At this point, my feeling is that I need to just let this one go. There is no rush for me to buy a bus, so I think I'd better just cool my jets and wait for the right one. I've definitely got an obsession going (I'm sure y'all can relate); so I have to control my impulse to buy one right away!
