Reasonable reply. J17, take note!
I'd disagree with not doing a test drive first, though. I had that once on a dealer selling an Esprit V8, a car I could happily have seen myself in but needed to know if the drive was any good before getting too excited. Dealer wanted to do the deal before a drive, so I simply walked away and bought a 350Z instead. That said, it's your business to run how you wish, and no-one can argue against that. If you're happy to miss out on sales by not doing the drive first, and are still making a good living, then I reckon that's the best of both worlds for you.
