Go to your local dealer and show it to the service manager, not the sales manager. He's interested in fixing it up. The sales manager is looking to sell you a new one. Even if you decide to sell it after its fixed, you'll have a record of what was recently serviced/replaced that you can show to a potential buyer. Be sure to replace the tires, even if they look brand new.
I didn't use mine at all last summer, but I store it in my heated building and keep a trickle charge on the batteries. I plan to use it this year, so I'll have my service guy check it over stem to stern and fix what needs fixing before I hit the road.
