mine gives me all 3 :hmm:
what to check... check (rear) guards, wheel well and A-pillars for rust - also will appear around boot hinges
being a car that has probably has not had the easiest life, make sure you test the clutch/synchros and check for signs of BHG. also keep an eye on the exhaust for blue smoke on cold start and also when warm during a spirited drive (see if you can get someone to drive behind you) this will tell you if the valve stem seals or piston rings are stuffed.
also another thing that shits me and is common with these cars is collasped driver's seat
other than that, you're pretty sweet - might have a small issues here and there, but what car doesn't hehe
