The list is long ....
1992 is likely to have had or is in need of some work on the chassis.
Areas to check are around the rear suspension, the rear x-member, the outriggers (they stick out of the chassis and hold the bodywork) and around the gear box x-member.
There are 'holes' in the bottom of the chassis that act as drain holes - are these still round (about 13mm in diamater) or are they corroed into larger different shapes.
Also the bottom of the A pillars (under the front door hinges), the bulkhead by the door straps and under the front vent flaps.
Lift the carpets and look at the floor panels especially where they meet the gearbox tunnel.
Check the battery box.
Check the fuel tank and the steel support strap and brackets.
Does the gearbox go easily into 3rd and 4th. Is 2nd and reverse easy to find.
Can you get into high and low ratio and does the 4WD lamp light.
Brakes are easy to change and not overly costly to replace. Calipers, pads and disks are around £250 per axle.
Steering boxes are similarly priced (for a refurb).
Check the condition of the rubber bushes on the panhard rods (hockey sticks) and the rear link mountings as well as the shock absorbers and A frame.
In gear, with the handbrake off, on a flat surface can you rock the car back and forth ? A little is fine, if the wheels turn by 1/8th (or more) rotation you have a lot of 'slop' in the transmission.
Is the engine/gearbox coated/dripping with oil ?
Look at the bottom of the doors also look around the door catches and see if these areas are full of holes or the frame is cracked.
Signs of rot are white bubbles in the paintwork along the bottoms of the doors and along the lower edges of the cars sides indicate that the steel subframe is rotting.
Look under and mats in the back - is the rear floor still solid and one piece.
Check the condition of the rubber door and window/windscreen seals.
Seats are expensive - what are they like ?
Engines typically outlast the rest of the car
Good luck
