Like these guys are saying, start out at $3800, and work from there. Even if you go up to $4200, that's still not bad for a 6 year (just barely) old bike with only 11,000 on the clock. That's really just broken in at under 2k miles a year. And, if the owner can show proof of maintenance, and it looks reasonably well cared for, all the better. Git'r done son!
