Something doesn't sound right here.
Given the market value of an R33 GTS-T, and the amount of stuff stolen, as well as water and other damage incurred, im surprised it was not classed as a write off by the insurance company.
If you were indeed comprehensively insured, your car should have been towed to a repairer, as GTST pointed out above, and you should only have been 'picking it up' when ALL repairs were fully completed and the car was like new.
