Welcome to the internet. There isn't more aftermarket support due to lack of demand, period. A handful of enthusiasts on a forum does not produce a market. Give it a couple/few more years.you wonder why there isn’t more aftermarket support for the car. Why tuners don’t want to deal with or advertise on here. Simple economics vs headaches. Let me know what I said was wrong that it’s better to go to the source before posting?
I don't think that anything the OP said was out of line. he stated that he tried contacting BM with no response, so if I were in his shoes I'd be nervous/upset too.
