TI see a 2006 with the black engine and only 7600 miles in the owner says it is in like new condition. I can't tell if it is a classic or not. It has windshield, leather bags, floor boards, and rear sissy bar with luggage rack. He wants $7000 which seems maybe a little high?
Look at Kelley Blue Book and NADA. $7K is quite reasonable for a 2006 with only 7600 miles. It's virtually new. If you can drive it, you could evaluate the transmission. You can also ask the guy to let a Triumph dealer inspect and test ride the bike at your expense. I sold my T-Bird to a guy from Canada who had me bring it to the dealer. Worked out fine.
I just put a deposit on a 2007 Classic which I bought on E-Bay for $7500. 6300 miles, Jardine exhaust, custom paint. It's being inspected before final payment.
