Sorry about the accident! That sucks man. Here's the trick. Have insurance total the car, and pitch them anything that will up the total value of the car like aftermarket parts, fresh rebuild on the motor, etc. Then you buy back the car at it's salvaged value. If you're lucky, the difference will be enough to buy a shell and transfer all your parts. Somebody on the site is selling a 2g for $1500 I think...I could be wrong. I bet you could find a broken down GSX for under $2k. It all comes down to whether or not you have the garage space, tools, and tech know how to swap everything.
Oh, btw, my advice on insurance is assuming you have good insurance. I have state farm and they paid out $3,000 for my totaled 1990 1g!!! I bought it back at the salvaged rate of $150!
Good luck!
. The good thing you came out ok. You can always get another DSM
