If you've ever sold a car on eBay you should no the figure it's at means nothing, 90% of buyers never contact you again.
If someone's stood in front of you with cash do the best deal you can and sell within reason.
I like wheeler dealers, it's about getting cool cars back on the road however the numbers add up, don't take it too seriously.
Seen many an episode with new brakes and tyres fitted and not listed but I guess it's cover for the TV company as safety so they can sell on.
