True, I do believe SOR is a frequent method that NJ uses to sell. However, in the now pulled thread, w17led did allude to the fact that the car was sold to NJ and that it had been straightforward to deal with him.
Given the number of CSL's that NJ has sold, I agree he would certainly have done his homework on this car and presumably it's a good'un.
It must have been a particularly scenic drive up to Abingdon from Crawley, 900 miles would have really taken in a few sights.....
