When it was still 735hp I used this as an example of the acceleration it had - If you're coming out of a village doing say 30mph and accelerated non-stop you'd be doing double the motorway speed limit in just under 10 seconds, it kind of re-calibrates your mind as to what is "fast"
I also find that in most "fast" cars I've owned I normally think "come on" when I floor it whereas this is more like "woah, slow down" all the time. I definitely have to read the road much more carefully now and it's amazing how much I now notice/react all the signs which warn me of potential issues (cross-roads etc) well before seeing the actual hazard.
