I've come across two BMWs in my CLK63 that stand out in my mind I was so impressed with the acceleration to 100 on them both. The first a gold 335d on the A1 that took a shine to me. I had the advantage but he never left my rear I just started pulling away at a speed I'd rather not admit to ! It had obviously been modified just looking how it sat low down and quite menacing even in the lame BMW gold. The other a white 135M on the A45 Coventry he was looking for a dog fight and was driving like a man possessed.I had to give it all I had to pull away then onto the M69 realised how too fast I was going on an early evening so decided to let him pass quickly followed by a Seat FR who wanted to join the fun.BMW diesel or petrol are formidable machines it's all about personal choice.The 135 M did sound quite nice on high acceleration when I dropped the window but nothing like the roar of the AMG.
