Low quality parts.
1.5L cars that is under powered.
Faulty parts found in the car.
Lack of safety features, no air-bags and ABS.
Cheap metals and plastics built machine.
The car is slow with it's acceleration.
Bad handling in sharp corners.
Vibration on the cars when exceeding 140kph.
Get a KIA Spectra instead, I rather pay more for a family saloon.
Proton produces the worst quality cars on it's class.
Gosh!!...to much complaint ehh??...if you want performance, why not you change the engine into the turbocharged engine such as evo 3 engine or vr4...
I believe that if you are exceeding 140kph in that car with that engine you are simply trying to find things to bag the car out about. it isn't designed for being a 'rev-head' car and maybe you should consider shaving the head and replacing the head gasket for better performance!
