I feel your pain mate. I reversed my car into my mates driveway (left almost 2 car lengths between my car andthe edge of the driveway, and there was plenty of grass as well) and left for 3 hours or so in his ute. Came home with a massive dent in my door and a huge scratch up the fender and front bar. Basically the door needed to bepulled out, the brand new side skirts needed respraying, the fender needed realligning, the front bar was scratched, and the head light was cracked. It wasn't anyone from his family, no one came to visit, he lived in a coulder sac so I can't see why they used his driveway to turn around. The best thing is, my car had a huge "For Sale" sticker in the front window with my number under it. But no, didn't get a phone call, a note, nothing! Left with a $2k repair bill for something I didn't do.
As for the insurance, $1500 is cheap. Mate, if you can't afford to insure it with full cover you can't afford the car. Even my pos S13 is covered with full comp. If the damage was less then $2k (excess) then fix it yourself but if it's more, then you're saving money.
NEVER drive an uninsured car! Other then that, good luck fixing it all!
