I had an 07 just sold last year with 46 hrs on it, scotts damper, plus all kinds of farkles on it with a rekluse clutch ( awesome ) and I sold it for $5K. It would depend if he had receipts and records. I would do a leak down test and compression test. Or at least bring it to a dealer and have them check it out if you are not confident in your abilities.
Just my worthless cents.
