Here's an update, although I know its long overdue. Haven't had any time to continue the project for the past two months. Regardless of that, its still alive though.
As I have mentioned, I was planning to create an LSSD version of the Caprice based on photos of an LASD one I've seen. Still a lot needed in terms of equipment but I have updated my Arjent to the S2 variant. Thanks to @Cj24 for the skin & @Ridgerunner for the spotlights.
