Probably the most reliable part of this vehicle is that I can almost always rely on a warning light turning on while I'm driving it. The 3-speed automatic is very jerky and doesn't always want to shift out of first and it is terrible on gas mileage. I average 19 mpg, which is worse than some high end sports cars. The interior is falling apart, the plastic components on the exterior have fallen clean off the car on a couple occasions. Within the first month of ownership both power seat belts failed and the front end electrics failed. These cars are also notorious for their starter problems. This is the worst car I have ever owned, I really should have bought a Honda.
Everyone can hear you coming from a mile away because it's a really noisy car.
More Research and Development, better construction, higher quality components, Overdrive for the automatic transmission, Remove the electronic and mechanical gremlins, better weight distribution.
