That's quite out of order. A test drive is necessary sometimes, but not to excess. Test drive is definitely not necessary after an MOT.
Some dude in his twenties who ran out of skill real quick. He should be fired; the company's insurance will take care of the car. Incidentally, I don't think it's possible for a 3-year old Scaglietti (must be 3 years for MOT) to be worth £200k; more like £170k-odd I'd wager.
