Two times I tried to repair a car at their spawnpoints.

First: All tires repaired, all elements in worn or better state, engine sarted but car didnt drive really good. Servermessage appeared that it will restart in a few minutes. Waited till server restarts. Car (Sedan) was gone.

Second: Sedan spawned near Tulga. Repaired 3 Tires, no battery, no sparkplug.

Both of them I putted something in their trunk.
