Crashed - Need Advice

Jason

Long story short: Someone tapped my back bumper, I spun and hit a guardrail.

Damage: Back bumper needs to be removed and painted. Front bumper, hood,fenders need to be replaced and painted. Driver side rim and tire need replacement. Front Aligment. Possibly some electrical problems (when I turn on my headlights, it smells like burning wires). Steering wheel airbag. Seat belt is retarded (it just stays stuck all pulled out). Some parts in the engine bay need to be replaced (I don't really know what they are but little plastic crap, bolts, plastic undercover, etc).

Advice needed: Ideally, I would like a new Z. I don't know if I have frame damage but they'll be doing a teardown inspection. Am I better off if they declare it totaled or fixable? Does anyone know how much I'd get if it were totaled? I was trying to find KBB prices but they dont have the Z on there (I don't think insurance goes by that rate anyway).

Just need some advice. I wouldn't mind just getting it fixed but I'm afraid of some frame damage and possible electrical issues.
