3000 miles isn't much on a well cared for TW, but on the other hand 5 (or 6? - depending) years and 3000 miles is also plenty of time to wreck a bike through abuse or neglect.
Even if it's in great shape, $2,700 seems high to me. I know the market varies around the country, but in this neck of the woods a brand new one can be had for $4000 out the door.
If it looks like a solid machine, I'd say try and get at least $500 knocked off the price and then go for it.
