This is definately a car that you don't just learn to drive over night. Besides getting use to the power,you need to get use to how it corners,breaks etc... I was pleasantly surprised at how it handled from stock. Car is very agile. Then once you start throwing on hp mods and suspension mods,then you have to learn all over again.
Tell your friend to take it out to a few autox events. Have fun with it at the same time learning how to drive it to its full potential in a safe and controlled environment.
