Yeah, I've spoken to similar people like yourself on a different forum, they agree that it is a great drive but as you say...pricey. Did you drive up to the top platform? that, I belive has quite a narrow road up to it, and the road in general is full of cars, motorcyclists & cyclists.
New discs, pads and fluid before going methinks.
I drove it some years ago and had no problems. I have to admit that,as a civil engineer, I was as impressed as much with the engineering as with the drive. We also put our boots on and walked up as far as the glacier since we, my wife and self, were there for the sight seeing really. The car, a Xsara VTS, simply flew up it. There again the cyclists weren't doing too badly either so I would have been amazed if it had struggled.
