Lot's of thoughts on that subject GTNJ. I've always run my new cars in gently for the first 1,000 miles - not driven it like grandma, but not redlined it in every gear either!
There was a very interesting and informative post a few weeks back that suggested driving it very hard to bed in the engine components was better than being gentle....
Who knows for sure?! I've had a few exotic and expensive machines over the years and have always been gentle with them to kick off with - the cars have been as quick as any other identical model, oil tight, no rattles etc.
Also, I'm afraid I just don't have the balls to sit in a brand new $350,000 Lamborghini and mash the throttle.... The same applies to the GT for which I have far more affection than any other car.
