So my car got really badly damaged and before last update 1.3 all I had to do was to fast travel somewhere else and call it boom car was magically repaired, but now no matter how many times I fast travel and call my car it stays damaged, in my frustration I tried to destroy it but somehow it is not exploding if anyone knows what to do please tell me.

Update: seems all you have to do is restart the game and cars repair themself if you call them

I've actually tried to blow up my car and then, when I called it back, I was charged repairs (about €$100) by some "insurer" and the car appeared fixed. Can't remember what patch it was though, I think 1.3...

I wish car repairs were so cheap in real life too, though...
