Seek a guarantee that there are no bent valves. As soon as you get it home, do the front of engine service. Crank it and check the compression. If you get any zeros, get a refund. If you get compression, drain the fuel tank, blow out the lines, replace fuel filter, take injectors for servicing. Change coolant, engine oil, gear oil, brake fluid. Take radiator for servicing/flow testing. Refresh engine vaccuum system. Refresh plug wires, cap & rotor. See if it starts.
Report back here before driving so we can talk about brake lines, suspension components.

P.S. If it were me, and the wiring were compromised, I would run away unless I was deleting the factory wiring (race car).
