Looking into buying a 2015 z6 with 900 miles. Anything g I should worry about. I know it's not going to win any races. It is for my wife and daughter to get around a little at some riding parks

[2015 Z Force 800 53/Trail EPS]

If it was taken care of the Z6 was a tough little buggy. Check the engine's compression, that it has an aftermarket foam filter, that the a-arm bushings are still OK, that the front diff locker still works, that the shocks are still not leaking and if it has any maintenance loggs, see that they were adhered to the manual's schedule.

It's is at a dealer. So far they have put an axle in it and that's all I know of so far. I go to look at it Tuesday. Thank you for the tips. Hopefully all goes well

The Z6 is an awesome little buggy.
Crawl underneath it.....It was tell you a lot on if it was abused.
Check to air box, remove the filter, check to see if there is dirt in the air tube. DUST will kill these little machines.
Drive it and run it through all its paces, ie. 4x4, diff lock, max turning forward and reverse.
Will the dealer stand behind the sale for at least a minimal time.
