x2 what Geetee said, GTO tags don't increase the value of a LeMans. Go look at the car if you are serious about buying, inspect it thoroughly. If you are not mechanically inclined take a friend who is. Cash talks in negotiations, when i am prepared to buy something i will always take the cash i am willing to spend (along with my buddies Smith & Wesson) and unless i am overly impressed by the inspection i will not go above the value i have set which means counter offering lower than my number for some room for him to think he did not get low balled. You will know immediately if your offer insulted him, if so walk away, he places to much value on what he thinks he has. Key is to do your homework before you go,whats a mint Lemans worth (comparables "sold" within the last few months not bluebook, reserves or asking prices)? What would need to be done to the car to get it to that standard ("i will need to do this, this and this to the car to make it worth what your asking".) His asking less what you will need to do to it should justify your reasonable offer.
