I saw the car too and was going to kid you to "give up, I'm going to outbid you no matter what..."
But the price has gone over what I'd be willing to pay for it considering the risk. A significantly overheated car may need a new head and also have cylinder & ring damage. From what I've heard, white smoke is typically water. An issue to consider is whether the oil was significantly contaminated with coolant. That might have ruined bearings.
I was going to go as high as $3K. If you are not going to go see the car, I'd at least suggest you ask them to send you pictures of all sides of the car and a close-up of the "small dent".
Good Luck to whoever buys.....
