My 04 M3 Vs. 06 997S (small point about ride comfort)
One thing I noticed about these cars on the same crummy road. When they're all warmed up. The Carrera has a smoother ride than the BMW! Less of the vibration and fewer of the bumps are felt in the Porsche! Kind of surprising, wouldn't you say? Both cars have recco'd air pressure and stock tires, etc., etc.. This one section of road should be a test track because they messed something up when laying it's foundation; there's a couple miles of consistent unevenness so it's perfect to make my totally amateur comps. Even my current wife noticed the difference. The M3 has the stock 18s too. Carrera has the 19s of course (but the overall BMW diameter is smaller by one inch). Wow. Niiiice car the Carrera.
