Having mentioned 420bhp, he went on the defensive and said that he wouldn't put his staff at risk like that. But that if I wanted, I could have another 10-15 minute test drive tomorrow, or have an M3 for the weekend, at a cost of £400, offset against the purchase of a car from Sytner. No compromise, 15 minutes in traffic, or hire one for a weekend for £400.
Testing the accelleration of an M3 is automatically dangerous? How on earth do these people sell sports cars with this attitude? Is it any wonder that so many "Ultimate Driving Machines" are 4 pot diesels?

Simplest thing to do is just to say "ok, thank you, i'll leave it thanks" and go somewhere else. When we looking for my mums BMW, we first went to Cooper Colchester and the salesman seemed hell bent on selling her a diesel and saying about how she'd get so many more MPG and how diesel is the future.
She said she wanted a 6cyl petrol but the guy didn't seem to accept this and kept coming back with print out's of 335d's then 320d's. Then she saw a nice 325i she liked the look of, but it was brand new and £35k. She just wanted to get a feel of what a 325i E90 was like but the guy was so reluctant to let her test drive it and was arrogant and smarmy, almost cold. In the end she got a drive, he seemed like he couldn't care less on the drive, took it around some 30mph roads then on a dual carriageway for a couple of miles then back to the dealership. It almost seemed like we were an annoyance to him.
She told him if he found any that were within budget, to give her a call, but we both weren't keen on his attitude.
Couple of weeks later we went to Elms Cambridge BMW to see another car (they didn't have it in stock) but the salesman, Simon Thornton, was a really nice guy and he went through what he had in stock and ended up selling her a much more expensive 09 325i. I think this was partly down to his excellent attitude and warm nature. We had a good running joke because i knew more about the car than most of them, but instead of getting offended/defensive as some salesman do, he went along with it, and any questions my mum asked him that he didn't know, he just handed it over to me

Would definitely rate Elms Cambridge.
This, to me, really highlighted the difference between a very good salesman (and importantly, one we felt we could trust), and a poor one and when i come to buy a car if i feel like i am a bother to the salesman i will politely retreat and go somewhere else.
