Transmission blew three times since I owned the car.
Water pump gave out within one year of ownership.
The car constantly overheated.
When driving over speed bumps, even the smallest bump, the car would always scrap.
Constant wiring problems.
Brake lights, blinkers, lights were always going out.
If anyone is ever considering buying a car, new or used, never ever purchase a Plymouth Neon.
They suck.
Although I haven't heard as many problems with the Dodge Neon, go figure.
Worst car ever? Go buy yourself a Peugeot, Renault or any French made car and You'll know about the worst cars in the whole wide world, maybe only rivaled by the Yugoslavian made cars.
