I have located a 2010 RT SE5 with 1700 miles on it. It has several professionally made and installed aftermarket accessories like highway pegs, floor boards, hand brake, etc. It is beyond the manufacturer's warranty period and the owner states there are no issues at all with the bike. The asking price is $18,500. He designs and sells these aftermarket parts and is selling this RT to buy a 2013 model so he can fabricate products for it. It is my understanding that he owns several Spyders, at least one of each model.

My questions are this:

Is this a fair price for the bike?
Is it a good idea to buy one that is out of warranty?
Can I purchase a warranty and if so, where?
Anything I should look for in particular for this year model?
Anything other advice you could give?

Thanks so much in advance!
