Haha. Funny stuff.
Comon guys, warranty a 1st year engine worth thousands. to make a 1300.00 sale? That's rediculous and as a business owner myself am astounded when people ask me similar questions in my own business. At best, he will warranty the xede itself, I would be very surprised if he warrantied anything else. He has alot of overhead outside of the hard cost of the xede itself.
Time to be diplomatic shiv, have fun.
