As an owner of 3 Neons, There is no way they belong on this list. 96 DOHC starts and runs like new with 250K on the odometer, 1 head gasket at 100K. 98 SOHC needs a clutch at 170K, still starts and runs like a clock. 95 SOHC met with a telephone pole and both died, luckily my daughter was OK, ran like a top and used no oil. Head gasket problem was 2.0 95-97 only. Once replaced with MLS head gasket you were good to go. Quick, great mpg, great handling, bullet proof. SCCA basically outlawed the 2.0 DOHC since it made everything else uncompetitive, they had it racing against V6's and V8's.
2.2 Chrysler was also a good motor. Always ran 100K easily.
British Leyland motors were OK, not as reliable as a Mopar, but not anywhere near the incompetence level as an aluminum block Vega or deleted oil feed Pinto engine.
Another truly bad engine was the 400 SBC, besides the round cam lobes, the lack of cylinder cooling from the siamesed bores made for a quick street death.
