Thanks for the explanation. I always forget about the cars being tested at altitude. You must be having fun with your turbo then even in stock form! Initially I had to decide between the M3 and the 335i. Placed my order for the M3 in May 2007 and in September my dealer phoned me to say they have just taken delivery of a silver beemer, but did not want to say what model it was, so off i went and was introduced to the 335i sedan. I drove around a bit with the test model and later that afternoon drove one out of the showroom! I think the M3 will always be an icon and i will always admire it but the 335i is a very capable vehicle and oh so understated!
Did not realise you were up in JHB. Hope you manage to get a few beemers together.
