This is a BMW not a Ford Pinto, the car was built for driving at high speeds. As long as you maintain the car well, let it properly warm up, and don't over rev it will last you a long time.
You can detect right away those that are going to be shaky, and that will fall behind and those that are very hungry, and that hunger you will have to develop. You gotta create a goal for yourself whatever that may be, a short term goal and a long term goal and you gotta go after that. And if you donít see it, and if you donít believe it, who else will?
