If no Carfax issues, the title is clear, and he is the original owner, or even the 2nd owner, I believe the price is very fair for an ultra low mileage SS like that. Of course the car should be in excellent condition as well. Sure, I would like it for $9,000 or $10,000, but if he is firm I wouldn't let an extra $1,000 stand in my way of ownership if I loved the car. Not many 'stock' examples around in that color with that mileage. I would grab it if it all checked out.
