As others have suggested. If the engine runs and it can be driven, you can make a lot of checks (see below) - if the engine can't be run for any reason, it does not mean there is a major problem, but it does mean you cannot tell whether there is, and this must affect your decision.
If the engine can be run, check operation of the engine, getting it warm. It should run evenly and start easily (first compression this time of year) once fuel system is bled if this is needed. Black smoke is probably not a major problem, blue or white smoke could be, same for uneven running or hard starting. It will be very noisy, but this is normal.
Check operation of clutch, brake all gears, high/low and four wheel drive. Check brakes work and don't pull. Watch for jumping out of gear, and strange noises (transfer case is usually noisy by car standards.
But I would take a good look at some of the other bits that will reflect how it has been maintained. Look at the spring shackles - the shackle pins should be in the centre of the spring eye, and there should be no sideways play. Check for broken leaves or leaves wedged apart by rust. Check the steering for free play - should be less than 5cm free play on the rim of the steering wheel, and all the free play should be in the steering box.
Check that all lights and other electrical equipment work, and look at all visible bits of wiring harness for signs of overheating. Look at the floor below the pedals for signs of brake fluid leaking. Check condition of seat cushions. Check condition and fitting of seat belts.
Check that the chassis number (should be on LH rear back spring hanger) is the same as the one on the manufacturer's plate (should be in front of gearlever) and the compliance plate (if fitted - most S3 have them - either near the radiator header tank or behind the engine). Different numbers mean you would be opening a can of worms - its probably a bitzer.
The biggest concern is probably rust - in the firewall or bulkhead, probably worst below the windscreen and near the door hinges, rust in the footwells is a lot easier to repair. In the chassis, look where mud would be thrown up from the wheels, rear crossmember, outrigger attachment points, top of chassis and bumper attachment area. Use a screwdriver to try and punch holes.
Don't worry too much about oil leaks - many seals will need replacing anyway just from disuse, but if the engine looks to be leaking oil everywhere, it probably has a lot of blowby, suggesting worn rings. Check prop shafts for worn U-joints and splines. U-joints are easy and inexpensive (splines are not) but the concern would be if they have not been replaced if needed suggesting neglect. Pull the level plugs on both diffs and swivel housings and see what is in them - if oil, you are in luck - if oily, probably OK, if rusty or water - expensive. If possible, jack up at least the front wheels, and check for free play on swivels and wheel bearings. Again, not a major expense, but a symptom of neglect.
Hope this helps.
