i had no problems with that dealer (i think it was the same one - near bmw and porsche garage?), very helpful etc. i did scare the poor sales man during the test drive though
other cars that i test drove either before getting the IS or since i got it (thought about changing / getting second car a few times)
Audi S3 - Two doors put me off
Honda S2000 - Again too impractical
Lotus Exige w/ 190hp kit - Nice but no creature comforts that I'd got use to (power steering, power assisted brake, air-con, switch controls not from a Mini!)
Ferrari 360 Spider - Lovely car, great to drive but a 4 year waiting list for the spider.
Lamborghini Diablo - Too wide, driving through central london made it feel like a small bus!
