Yes, the early 90’s Corolla – my own daily driver – did a pretty good job at being diy’er friendly. Oil, oil filter, air filter, gas filter, fluid checks, all easy. Spark plug replacement a 20 minute job. Checking valve clearances, maybe 40 minutes. Alternator and front brake pad replacement a breeze. Brake master and clutch master replacement fairly simple. Rear drum brakes, starter motor, water pump and timing belt replacement, those are not so easy jobs, but still within the range of an experienced diy’er properly tooled up. Engine computer diagnostic codes blinked out on the dashboard, no need for a scan tool.
So ideally the car I’m thinking of would be something like that, but with OBD II functionality, and a factory-level functionality scan tool configured for only that make/model/year that comes with the purchase of the car. And free on-line access to the factory service manual.
