Unfortunately it appears to me that the bottom line is that it doesn’t matter whether it was from BCA or any other auction , I think a judge might say that as a professional car dealer having PDI’d the car ,you have forfeited your chance of making any further claim regarding a misleading Assured Report by retailing the vehicle with known faults to an innocent member of the public.
As a newbie,you will need to factor in that with on line buying you should find that you get far more bonuses than penalties so just ‘ take your medicine’ and move on.I might add,if this is your first year operating on your own,even if you have been in the trade as a salesman for years,be prepared as you might be faced with set backs you never even thought of.
So good luck and ‘welcome to the jungle ‘ and don’t be put off.
