Jbeam wise yes, but we are not touching most of the model, only things that have significant visible shading issues, or that need to be separated for easier reuse. Materials stay the same for now, only most converted to json to read them easier. And will have to redo skin UVs and all skins too. The refreshed ETKs were also significantly modified Jbeam wise. On the 800 the only things untouched were the mirrors, fuel tanks and front bumper support.
I tested the caprice in 0.29.1 and the only thing broken is the glass textures and the headlight textures
All the openable stuff, thankfully the hood was the only thing that needed a major rework, the rest already had correctly set up hinges. (Also added a spare tire.) I can move to the interior now, which needs a huge rework Jbeam wise.
A Royal Monaco would be better, as you can see from my profile image, and no. Sorry, no one takes mod suggestions unless it's a meshslap.
apparently a limited amount of 6.2 diesels had a test run in 81 in cars so the 6.2 swap is actually realistic
