Chassis looks in great condition!
Have they provided a list with what has already been changed? e.g. fuel lines, brake lines, coolant hoses, radiator etc? Obivously it's a runner, does the A/C work? Do both driver and passenger side electric windows work?
Front suspension lower control arms look to be stock, would recommend beefing those up with the
reinforced versions at a minimum, or the
milled ally arms if you want the best of the best. Upgrading the
front anti roll bar with the poly bush kit from DPNW.
Rear end, change the
trailing arm bushes and trailing arm bolts (would recommend the Inconel TABs, fit and forget - I think the club has some of these, but they are not currently listed on the club store, Arran?)
Being a stage II it's got dual cats on the exhaust, but those could be chopped out as we have no requirement for them in the UK on cars manufactured before 1991.

What's the rest of the interior like? Roof centre/rear headlinings for example?
Door cards from what I can see look flat, but that's normal on any car you are likely to find for sale, it's an easy enough DIY job to refoam them. Multiple examples in this thread here:
