All the turbo engines are exactly the same regardless of spark plug cover.

Watch out for smoking turbos, knackerd lamba sensors and crank sensor.

4x4 system is made by fisher price and most dont work and have been converted to fwd.
If its low with camber at the back wheels, chances are the transfer box will be knackerd, best bet is to find one with an uprated transfer box.

As for rust, check under the rear spring cups, sills, arches, well everywhere tbh.
