I added the standard Vehicle Mod to my unmodded Game of CoP many years ago once I reached freeplay in one of my many Games. The coolest thing I ever saw is when my vehicle would enter the grounds of the "Iron Forest". The Poltergeist there upon detecting my presence, who would usually throw random loose things at the Player, instead made the vehicle I was in levitate. Having nothing to throw it at, the levitation would involve me rapidly rising through the air hundreds of feet until I got beyond it's range where I would unceremoniously drop to the ground usually in an explosion and my death. A few times I would survive. Eventually after many tries I survived and was thrown over the invisible barrier to explore the restricted areas of the Map. Good times. https://i.imgur.com/dinjzRY.jpg https://i.imgur.com/1ZFQaBX.jpg
I spent two days editing the vehicle models to add working headlights, missing elements and make parts breakable in the SDK.
All the models are taken from vanilla Shadow of Chernobyl, with the exception of the Lada (taken from OLR) and the Raf (also taken from OLR, with some elements of the cabin ported from the Lost Alpha model).
A minor, but important change was to the BTR model. I opened the driver hatches, which means the headlights can work properly.
