hmm interesting. who was at fault at the accident? I had a accident in my 350Z where someone bumped into me at 75 MPH and totally made me do a 360 in a crowded highway
. Long story short, I was told by her insurance company (21st century) that I can have a rental car as long as I want until they fix my car. Not only that, they told me I can get w/e rental I want! Now that's a good insurance company!
If it's the other persons fault, his insurance company should provide you with a rental until your car fixed. If it's the body shop that screwing up, then have them get you the rental (tell them to talk to the ins company).
