My old man had a 323i (basically a de-tuned 325i) sedan. It had an aftermarket exhaust and was tuned. I could hear him coming from a mile away, so I knew when to shut of my NES and get back to homework.
I got mst rmx 2.5 bmw E30 couple weeks ago and i am having problems with it first one is that it doesnt accelarate wery well and it cant hold drifts more than 3seconds
