I think that stuff will cost at least 7g+(labor is the killer, trust me on this). Dude if you have insurance, let them handle it, thats what they are there for.
Also, how much is your 323 worth right now??? If to fix it, it will take 50% or more of the car's value, it is a total loss. It looks like it could possibly be, depending on how badly the frame is bent, and what else you damaged. You have a chance of taking the cash and getting a new car, if its totalled.
PS. Your car wont start b/c there is no MAF sensor or any of that shyt......
