Well from what i saw it's got a lot of tell tale signs of a GT, probably dealer optioned.
Factory A code, 4 speed, 3.0 rear end,
Body in average condition,
Steering box,
Prop Valve,
Exhaust hangers both under rear seat and frame rails,
Camera case cluster and glovebox,
Fog lights,
Steering wheel there but not fitted,
GT guard badges not in correct position, missing side stripes, Fog light switch not in correct position...
Is it worth the money
