TTT - // They call themselves WBAC and they do but they don't actually want any car, they want the ones that will sell at auction for a profit, usually to the fringe motor trade. They'll buy the others even the scrappers but they'll try and wriggle out by offering a low price. //
This is a common business practice.
There is a chain of shops who used to be known as Records And Tapes Exchange, and their advert used to boast something like - not a direct quote, but the sense is here - "We buy any records, absolutely nothing refused …" which sounds really good.
Of course, the price they offer you may not be what you want to accept - yes they will buy your cherished collection of Tight Fit and Goombay Dance Band albums, but for 1p each! This allows them to watch you refuse, and leave with your albums, or to buy them, and sell them on at 1p each, losing no money in the process.
I am sure the same principle applies with WBACDC - yes they will buy your car, but it may be for less than scrap value, and you are not interested, and they are happy to let you drive away again.
