Looking to buy a new "used" rider this season. I found one in my area that is going for $6000.00. Its a 2002 61" Scag that has a 27 hp Liquid coold kawi on it. The guy told me (and showed me) that he paid $8126.00 for it. He also told me that last year he blew a pump and paid dearly for that also (showed receipt). Now my friend has worked on and off for him and he told me that the maintenance on this machine was always maintained every 6 months, needed or not. Is 6k too much for it or is it in the ballpark. I was looking to spend around 5k but this is a nice machine and has potential for accessories. What do you think?
