In general, there is nothing wrong with car. However, there are some minor problem such as the power window. The power window malfunction 2 day after I brought the car. I just feel uncomfortable with the service given by proton services, the so called proton adviser are not professional at all. They always said "biasa punya" or "this is a proton is not a Toyota, so problem occurs is normal". It seem to be the so called adviser is not work for proton. I just done my 20,000 km service because of their bad service, I have decided not to send my car back to proton service anymore. I rather pay more to outside workshop to service or fix my car.
I would recommend you to service at individual dealers who care more and service is quick.
