Unfortunately I've created a rod for my own back. The RAC Assured scheme gives a (perceived) quality assurance to customers (and I've already had an increase in footfall with people saying it's directly because of RAC that they're there). The downside means having to sometimes reject cars on economic grounds. The car I was whingeing about was a perfectly good retail car (and sold too!!) but was just one of those where all the small bits that we normally shrug off and do came together in one massive bill. Returning the deposit hurt but I traded out of it for a small profit so I really shouldn't complain.
