When Otto announced the 1/12th scale E30 M3 DTM car, I contacted them and asked about an ETCC version.
I don't remember when the M3 was originally shown on their website, but it must be a year ago at least.
This reply arrived in my inbox this evening.....
Many thanks for your suggestion! I will transfer your message to our Development Department so that they can study the request.
The new models are announced by newsletter.
We can’t guarantee that you will receive an answer from this service, but rest assured that your request has been taken into account.
Thank you for the interest you show in our company.
At least they answered!
