Man, brings back memories of my '83. Not all the memories are good. 
Anyway, looks real clean!
Every so often the O2 sensor light will come on. If you remove the instrument panel surround and look on top of the cluster with a flashlight, there's a lever sticking up (IIRC it's on the right) if you pull that forward with a piece of safety wire etc it resets the light and it's good for another 30K miles.
The oil pressure warning systems have been known to go off for no reason, it scares the crap out of you. Disconnect both sensors, use a mechanical oil pressure gauge tapped in at the head fitting and drive on.
The engine mount at the timing belt side will collapse, this makes everything in the car buzz like crazy particularly with the A/C on. The mounts are cheap (~$15) but last only about 10K miles. They also have to be pressed out of/into the bracket.
New bushings tighten the shifter up tremendously but like the engine mount they don't last very long. Also check the alternator mount, they used urethane? bushings which will wear and make it spit belts.
On mine, the seat back 'rake' adjustment (the knob on the outside at the hinge) continually changed itself and nothing I did fixed it. But the seats were among the best I have ever driven in. Supportive, firm, good bolsters.
There's an aluminum plug on the CIS distributor between the dizzy itself and the rubber air boot, if you drill this out you'll find a 3mm Allen bolt under it. This is used to adjust the mixture and you can use it to pick up some HP and low speed driveability. Then plug the hole back up with a blob of silicone. Of course, if you have emissions testing you shouldn't tinker with it.
