One of my nominations for worst
1995-1999 Dodge/Plymouth Neon.
Were a hoot to drive and were quick/sporty compared to most if not all cheap compacts of that era. Unfortunately the head gaskets were a problem for most of the model run (finally fixed for 1998 or 1999 model years), frameless windows were rubbish and were pretty much guaranteed to leak water or wind, weak engine mounts, peeling paint, etc. Lets not forget the old hydraulically controlled 3 speed TorqueFlite, yes it was reliable but it killed fuel economy and pretty much everyone else had moved on to electronically controlled 4 speeds - I think Chrysler and GM were the only holdouts with 3 speed autos in the Neon and Cavalier but at least the Cavalier you could get a 4 speed. Lets just say that generation Neon were all throwaway cars at 100-150k miles IF that.
