I'm leaning towards it, I didn't the current M3 since its a V8 and not good for a DD for me. But if I do get the M4 then it can be my DD and I might keep my e92 335xi as a winter car or sell the 335xi and get an Audi A3 Quatro for winter
But I will not get the first year for sure as history shows cars or electronics will always have some unforeseeable "issues". I am in no rush, but for sure I will do ED again!
