I'd be looking at the fuel filter before you start chasing engine problems. Brakes are easy ... the accumulators will probably be dead ... so the brakes will be full of nitrogen. Bleed the brakes so you can move it around safely. The LHM level is probably really low if the rear doesn't lift... Either that or the height corrector is a little seized, try moving the lever around a bit (it hasn't been moved with a forklift bending the linkages under the car ?).

If it's distinctly running on two cylinders, check the coils ........ Um, is it a twin coil ignition or the earlier system ??

As for rust ... we have plenty of cars to chop repair sections from for you
