Time to renew the lease car. For reasons that are no ones business but my own, I drive an automatic.
For reasons that are also my own I refuse to buy a car without a test drive.
So why are sales reps in new car dealerships surprised and a little bit tetchy when I walk away if they tell me they won't source an automatic for me to test drive ?
Age, I guess 
So as a general AIBU ... if someone expects you to part with the equivalent of a deposit on a decent house without having a chance to try one out ... who's the unreasonable one ? Me for walking away, or them for expecting me to just buy it.
(The best one was a dealer who told me it would be "easy to imagine how an automatic would drive" ... to which I noted it was also easy to imagine winning the lottery and buying an island, but that wasn't going to happen either ....)
