Our 325 had 5420 miles on it. It's possible. First, check the tires. They have probably have been replaced,but still at 9900 miles, your brake rotors should look like new, as in no ridge on the outer edge. Rotors should be smooth too. Frame rust should be almost nonexseistant. Engine should be spotless, as in valve covers should be clean ,not rusty, tires should have a lot of dry rot,if they ar original. Check the dot date on the tires.
Check the steering components. Very little grease should be on the tie rod ends.
Stuff like gas lines rubber brake lines will look old and starting to crack.
If this coach has a lot of miles on it, but a new speedo, that now reads 9000 miles previous owner I would think replaced all of this stuff. Dj
