We had a customer call about a 640d with a px, we offered 7k for the px only to be told it was way too low as what car said his car was worth £9600. So we ended the call. We thought it would be nice to see what they valued our 640d at, we had it listed at £21990, what car said the retail price should be £26800. So we called the customer back and told them the good news, we could offer £9600 for the px however we would want £26800 for the 640d, they weren't so keen on this deal either.....
