If it helps I booked a test drive with them last week. I turned up with my px my wife, my mother and my father(as they were down for the weekend). I had a look around was shown around the car and given the keys and the trade plates. While sat making myself comfortable and making sure the car was ok to take out the salesman re-emerged and told me that the manager was not letting me take the car out unless I bought it.
Suffice to say I got out and walked off and bought the very next Z I sat in actually. I just really really wish I had read the above thread before I went there as I wouldnt have bothered. Its your call but.......
