I stole a C6 Chevalier I think it's called from a roadblock event that spawned, and for some reason when I left and came back it changed its color to white (it was completely black initially). Nothing else seemed to really change; the trunk and spare seat still had my stuff in it, but I just found that odd.
On a secondary note, (and I'm sure you're already aware of) any vehicle spawned in a roadblock is guaranteed to have 100 engine quality, which is far, far higher than it should ever be of course (for reference if anyone else is reading this and is confused, most civilian vehicles have around 25-40 engine quality as a rough estimate, and generally vehicles never go higher than 70 engine quality)

Thanks for the great mod.
