Kinda blows how someone car smash into your PARKED car and you still have to worry even a little bit. In cases like these the person responsible should have to pay as much as neccesary to get you back into the exact same thing you had, nothing less.
When I got rear ended in my 82 Jetta, I got nothing for the car (276K, previous write off several times) despite the fact that I worked my ass of making it look and drive like a new car. I pleaded that case to SGI and they were kind enough to give me $1500 for the car insead of the $790 they were originally going to give me. That was probably still one of the saddest days I can remember because that's when I decided to call it quits on the Jetta (I still have it, just stopped trying to make it better)
Hope you have better luck with your insurace
