This is a Carbon Motors E7 of the SCSD. A few months ago, I built one of these on LDD, and yesterday, I updated it and built it, so here it is! I believe it is the first Carbon Motors E7 to be built in Lego. I also plan to build at least one or two more units for the SCSD, and I have four that I have already built on LDD to choose from, which will be uploaded to MOCpages later today.
About this creation
The whole SCSD fleet.
With today's other addition to the SCSD, a Ford Explorer Police Interceptor.
Great, but there are two problems. First, you said this was due back in August, which you didn't update about. Second, if you really want to be realistic, there was only one prototype ever made, which I doubt they would lend to a PD. But, very nice build overall, and very clean.
