That sounds like a fair price for an 85, especially a good runner. I would take it for a spin to see if everything works. A 45 minute drive is nothing. I have drove 3+ hours one way to pick up a p.o.s. , but hey, start a new project, and make it into somthing nice. If I were you and had the cash, and didnt have much to ride, a 250R would be a great machine to buy for sure!
