discs and pads are reasonable money, i totally agree, tyres aren't that bad, they are low profile, wide and fit on sizeable rims.

it's the fuel costs that will kill it, i plan on an m3 when the weather turns and i trade in my 330ci, but already realising a 3.0 straight six is thirsty and m3 isn't actually much worse for so much more potential.
they are making quite a bit of sense right now and there are many good ones out there ready to be used properly.
