Have just picked up a 22RE Corona as a daily driver. It's nothing special but is generally in good condition. Drives perfectly, blows no smoke, doesn't miss at all under any throttle/load conditions, and fuel economy is commensurate with a light truck so there are no complaints there. The only problem it that it's a bit tricky to get it to catch when starting (mostly when cold).
Haven't had much of a chance to look into it as yet, but am religious on servicing so I cleaned the air filter and gave it new oil, filter and plugs at first opportunity after picking it up. I won't get a chance to look further at it until next weekend, but I've earmarked:
* new fuel filter (sixty bucks, ouch!)
* check leads with multimeter
* new points, rotor button & dizzy cap
