i think if you release these, you should release both separately (and remove those damn covers on the second one's headlights)
Dunno if it will ever be released, I have had very very little luck with blender vehicles in the past
If I do release it;
I want the car to have a startup and shutoff state, engine sounds, hood/trunk/doors possibly open, slow to fast speedup, etc
and upon startup; the covers would open
