I've made some progress on the Starion:
-All stock body parts are in (apart from the wing)
-All stock windows are in (apart from the sunroof)
-Rear badging is in (everything from FM4 anyway)
-Pop-up headlights are in
-Taillights are in with working glows
-Stock steering wheel is in
-Stock driver's seat is in
-Stock mirrors are in
-Stock widebody sideskirts are in
I've also made various fixes to different things


The lenses on the tailights are separate, so you can replace them with different styles (tinted, without lines etc) without having to replace the entire light.
The taillights also don't have light orbs, but I personally don't think they would look right seeing as there's such a big amount of red already on the light glow as it is. After all, the glow is basically flat, so a glow wouldn't add much depth to it.
The pop-up headlights are in-game, but I don't know to make them pop up automatically when the lights turn on. I know that this has been done with various mods from people like BB93 and RedCarDriver in the past, but all the animation javas are missing from them.
If anyone could help me with making this work, please let me know by replying to this post or PMing me.
Spoiler: The Conquest was literally a badge-engineered Starion for the USA. This ESI-R would be identical to their Conquest TSi, apart from the Plymouth/Dodge/Chrysler badging outside and in.
It wouldn't be difficult to add a Conquest variant, not only because there are no major differences, but because this model is already left-hand-drive.
