OK, let's review:
-Valve cover gasket appears to be leaking, rec. replace and monitor for other possible leaks: Easy, less than $20 part. Good photo-op.
-Crankcase vent hose appears to be seeping, rec. replace: If it is the one that takes the place of the PCV and goes from a tube on the VC to the intake snorkel, that is super easy and cheap.
-Power-steering low-pressure line appears to be seeping/leaking, rec. replace and monitor other possible leaks
-Power-steering pump also appears to be leaking, rec. replace line first and monitor pump for possible leaks: The ZF PS reservoirs in these cars seep. They just always do, no matter if you reseal them or what. Id probably do the line and the cap gasket, then watch. It only takes ATF, so I wouldnt worry too much.
-Differential rear cover appears to be seeping, rec. reseal: Agree, but not due today. I would put new fluid in though so its fresh and youre topped off.
-Transmission appears to be seeping/leaking from shift shaft seal and output shaft seal, rec. replace and monitor for other possible leaks: Same as for the diff. Use Amsoil MTF. Easy.
-Cooling system appears to be seeping, rec. diagnose possible leak: What is?
-Coolant staining found around expansion tank: Is the expansion tank built into the radiator? It is on mine. Check cap gasket first.
-Belts appear to be age-cracked, rec. replace: Agree. No biggie.
-Front brakes have approximately 3 mm of material left, rec. replace when light is illuminated: Front and rear have lights. Nothing to do here.
-Rear brakes have approximately 1 mm of material left, rec. replace when light is illuminated: ditto
-Brake fluid appears to be dirty, rec. flush as per BMW spec :agree, clutch too.
-Resonator and muffler both appear to be rusted and rattling, rec. replace exhaust system: Pass smog? What is rattling? The rubber donuts get soft and cause the exhaust to sway. Id check all hangars first before removing.
-Rear shocks appear to be original, rec. monitor for possible future leaks: OK, nothing to do.
-Rear shock mounts appear to be original and torn, rec. replace: easy.
-Rear trailing arm bushings appear to be original, rec. monitor for possible future tearing: OK
-Rear sway bar end-links appear to be original, rec. monitor for possible future play: OK
-Front struts appear to be original, rec. monitor for possible future leaks: OK
-Front bump stops destroyed, rec. replace: Agree
-Front lower control arms appear to be original, rec. monitor for possible future play: OK.
-Front lower control arm bushings appear to be original, cracked, and torn, rec. replace: This may get pricey, but worth it.
-Both tie-rods appear to be original and have excessive movement, rec. replace and align vehicle: Easy. I got moog ones and have been happy.
-Front sway bar end-links appear to be original and have torn boots, rec. replace: OK, easy.
-Rec. align vehicle: Do it at a BMW shop, there are specific weighting procedures.
-Flex disc appears to be original and oil-soaked, rec. repair oil leak first, then flex disc to prevent future oil-soaking: Watch this one. Concur.
-Engine mounts appear to be original, sagging, cracked/torn, and oil-soaked, rec. repair oil leak first, then engine mounts: Agree, but no big deal.
-Transmission mounts appear to be original, sagging, split, and oil-soaked, rec. repair oil leak first, then transmission mounts: Agree.
-Fuel filter appears to be original, rec. replace: super easy.
-"Inspection" light illuminated upon arrival, rec. perform proper Inspection service: OK, easy to reset.
-Engine oil appears to be leaking badly from front camshaft seal, rec. replace and monitor for other possible leaks: How much $$$ for this? Id say this needs to be done first.
-Timing belt age is unknown, rec. customer check records to see if belt is due to be replaced: Concur.
-Oil pan gasket appears to be leaking, rec. replace leaks furthest forward and upwards first, clean, then monitor for possible leaks: this is an easy replacement. Concur with plan.
-Oil filter/gasket appear to be leaking, rec. replace and monitor for further leaks: Easy.
-Alternator appears to be a newer remanufactured unit
-Radiator appears to be a newer aftermarket unit, "Made in Spain" printing was found: OK
-Shifter found to be sloppy, rec. shifter rebuild: Agree
-Transmission may have internal issues, 5th gear detent: Could be serious.
-Third brake light does not illuminate upon brake application, rec. diagnose and repair: Agree.
-Clutch pedal appears to stick intermittently to the floor, rec. diagnose and repair: Is it sticking, slave cyl or something else?
-A/C compressor clutch appears to not engage, rec. diagnose and repair: Do this if you decide to keep the car. For your climate, may not be needed.
I think you could learn a lot with this car, only very few items are actually serious. The rest are fairly simple DIY.
