From a reliability and cost of ownership perspective, best by far was my '89 Corolla. Bought it for cheap from a friend at a low point in my life when I just needed cheap transportation. Had 112K on it. Drove it to 230K and only repairs it needed were CV joints (super easy to replace both front axles, had the whole job done in under 2 hours) and a water pump. Don't know if the clutch had been replaced before I bought it, but it gave up at 230K so I had it replaced and just a few days later 3rd gear in the transmission broke. I never once changed the oil in the trans, so guess that should've been expected. Could've put a used, guaranteed trans in it for cheap but I was tired of it at that point so traded it for an '06 WRX that only had 38K miles on it. That was the second most fun car I've ever owned behind my '72 Formula. That car was also very reliable, no problems other than the heater blower motor gave up at 50K miles. Easy fix and no other problems until about 145K when the clutch was starting to get iffy, the catalytic converter was getting plugged up and it blew a head gasket. I had pounded on it for over 100K miles at that point so felt like I got my money's worth and rather than spend the $5500 to put a whole new engine and turbo in it, I just sold it.

Worst car is a tie between my '84 Nissan 4x4 pickup which blew the transmission and kept cracking cylinder heads or my current '97 Accord that has had all kinds of stupid stuff go wrong with it.
