I would so love to see their "flagship" vehicle come unstuck.
Imagine; they are pulling into the pits, brakes smoking and the fuel light on: "Sorry, your service account's been suspended". Charging them a listing fee to sit on the grid. Charging them a fee if they ascend the podium, then a percentage of the trophy value.
When they come into the pits, trying to fit similar parts for a completely different car: "You might be interested in..." If the car has a genuine problem, not heeding the evidence before imposing a decision on the remedy.
And best of all, forcing the "return" of the car to some foreign person with enough bona-fides to prove Fleabay bought it off them and never paid...
