    Hey guys, So recently I removed (with some difficulty, thanks aluminium+steel..) the 7j 16" rims that came standard with my E46, and slapped on a set of 8j front 8.5j rear 18" rims off an E46 328 M. Now, I'm not sure if it's just me getting desensitised to the acceleration or if the new wheels...

    Hi, Just thinking about getting a BMW 2 Series 220D Active Tourer as my new company car. I have had a 520D for the past 9 years but the 2AT would appear to be far more practical for me now (I know the change to FWD might be a bit different!) but I just noticed in the brochure that it has...

    Hi I started my car that was parked in rain and cold weather for about two days and moved off almost immediately after starting, without waiting for it to warm up (I know probably shouldn't have done it :p).
