I agree, the M340 is more than fast enough for DD,
but nowhere as dramatic (brutal) as an F80 during hard acceleration. If that's your thing, go
with another F80 till the G80 is out. I haven't seen too many '18s around, a lot of '19 M4s
If I tracked my cars, and did more highway driving, it would be a no brainer for me... mundane city driving, basically anything less then 50mph was fatiguing after a while (on a daily basis), with the M4. I kept it in sport+ a majority of the time...
For me this is a nice break, I don't need to feel every bump in the road, and NVH.. also, the crazy part is, with regular DD (not talking about the track!!), which for most people is 90% (maybe slightly more?) of the time.... the power differences between an F80 and G20 is negligible... in those cases I believe a G20 will give an F80 a hard time!! Pssst, don't put that on the "M" forums!
