Thanks Grouse;
I did do a search, but probably used the wrong words.
We don't have much experience in buying used. Only bought one used car in my life (turned out to be a good deal).
We usually buy new cars, keep them for ever, then sell or give away the old car. The only other experience we've had was buying a used airplane, but airplanes are required to have regular maintanence and be certified for flight, so that makes it easier.
Thanks again;
