There are plenty of dealers, I wouldn’t personally rely just on Richard Symons as he seems more interested in pumping out videos. They’ll also all tell you they’ve a list of people wanting to buy, but how many of them do you want to ring up?
A dealer will look for a couple of grand to flip the car for you so say 62k sale at Symons or Wisely or Simon Jones is about £59,500 to you. WBAC seem to be offering 58k and you walk away with the cash that day, and Motorway will take a week or 2 and you’ll probably get somewhere between the two.
So if you’re not prepared to sell directly I’d get a price from Motorway. You’ve put the dealers in competition with each other rather than them trying to become your best friend while all they really want to do is flip your car as quickly as possible. Symons et al will be all over motorway and every other source of stock anyway.
And WBAC is worth a punt as a back stop price.
