White i see your sense of thinking but whether or not a dealer would is a different story, they can be a funny breed sometimes! i think it all depends if you get a salesman that is actually on the ball and can see a benefit of changing. The only thing to do is find out first hand mate, give it a go.
When i test drove one i couldn't get enough of the sound either, it was the sound that sold me at the time but it was the pace that didn't. It just felt very slow!!
