Certainly not acceptable on a 62k base M3, leave aside a 90k one
IMO in today's world the whole car buying process is so different. You don't even need to go to a dealership anymore or meet anyone as everything can literally be done over email. When planning for my 2016 ED, I contacted over 19 dealers and that included David. I never heard from him but the pricing from the west coast was anything but competitive. I was able to secure a 1k over invoice deal from a semi-local dealer (40 miles) and he came through for me on the same day that allocations were released. I already have a production number and I have still not spoken with my CA over the phone. Everything was over email
