Nope. No more than buying a £75,000 Bentley makes you a better driver.

I got to drive an Bentley Continental GT last week... 12 cylinders, twin turbos, tweaked to 611HP... OMG!!!

My normal driver is an 06' Suzuki Aerio.... I believe the Bentley made me a better driver in many ways :) mostly in the passing other cars catagory!
