"Oil changes every season" What does that mean exactly? Four times a year seasons, or every riding season, which could be once a year to someone.
Check the frame for cracks at the welds.
Take the seat off and see if the airbox has a lid on it. Don't be alarmed if it doesn't, many exs with an aftermarket exhaust, run without a lid to improve performance. If it does have a lid, take it off. Lid or no lid, if the airbox is dirty inside, that shows a laziness in their maintenance routine, and personally, I'd pass. No matter what their story was.
Take a floor jack with you. Jack up the rear, start it up and put it in gear. Do the rear wheels wobble? If they do, it's either got a bent wheel, bad bearings, bent axle, or some combination of them. Just so you know, when I jack mine up like that and put it in gear, the wheels still turn with the clutch applied. Once the tires are on the ground though, the clutch works fine, just needs some resistance.
Since you aren't in any hurry, offer him hundreds less. Just don't low ball him so far that it's offensive. He has probably already figured some haggling room, into his asking price anyway.
I suggest putting nerf bars on it. Sure they'll make it look cooler, but most importantly, they offer your feet and ankles some safety.
