I plan to buy the Persona H-Line. Today, I went to the proton edar showroom and test drove a M-Line. The accelaration was not smooth or rather inconsistent as it was like slow start and out of a sudden rev high high and changing of gears not really smooth (auto). Don't exactly know how to explain this but is this really on all Personas or is it only on this car?

The steering wheel on the PE feels cheap, any recommendations for a good one? If I change it, will my warranty be voided?

Haha, I really did not think of that. I know nuts about cars.
