May need a little more Info on what type Of Mitzty it is, !! There are quite a few different models Re - what Cab/Chassis it was Built on, Diesel or Petrol, Manual or Auto, also year of Manufature, Mileage, and service record, All important to know,
It's a motorhome. Yes, I have a vehicle with a fair few miles on it but I service regularly and look after it but I know if I wanted to sell it people would think it would have done lots of k's so it must be no good. I guess you just have to get it checked out and hope for the best.
Thanks
