You proved your m3 was quicker than a 500 hp m5 with worn tyres and mega slippery track, I think buy csl for great looks rarity value nice carbon bits sound of course the sound is what keeps me hooked the nice duck tail spoiler feels nice when polishing
the thin glass back window special suspension changes spring and damper rates set perfectly for the ring the whole package really, it wont be night and day difference to yours but believe me you wont regret it just keep it clean to treat it mean.
