When last we checked in at Dinan in 2015, founder and owner-operator for 36 years Steve Dinan had sold the company and left for Ganassi. He stayed on as a consultant to the entity that bore his name, and much of the staff remained in place to do the testing, tuning and development work, but still, things could've been a little different. Then last year, one year after Steve Dinan’s departure, Autoweek tested a Dinan S3 M235i and found things mostly to our liking, so maybe all is well.
Then a week ago, a friend at Dinan called and asked if I’d like to drive a Dinan S2 M2. With your best interests in mind, dear reader, I said yes.
