I have a loaner right now, it's a base 328i. I drive it the same I drive mine only I floor the 328 more because i'm use to the power of the 335i lol. But since I've had it (it's been 4 days now) I've filled it with premium AND i've hand washed it. Also, I'd imagine a lot of BMW owners are older and have the maturity to not drive the car like an idiot. It's those hoodlum 1 and 3 series owners that destroy everything
