BAT is a PITA! My biggest concern about BAT is that you can't speak with a live person like you can on PcarMarket. Everything is done by email on BAT. Then they have to decide to accept your car. If you get accepted it takes at least a month to go live once they have all your information and photos and there is only vague communication about it: comments like "our team is hard at work on it." Then, once you do go live, they don't hesitate to post another Speedster for sale, even on the last day of your auction. THAT SUCKS!
I find it hard to believe that the bidders on BAT aren't aware of PcarMarket.
The "ripping it up" you see on BAT is mostly Vintage Motorcars Speedsters which are more valuable right out of the gate.
And FYI, it appears that there is some behind the scenes negotiations and Robert's car is probably sold.
