I borrowed one of these yesterday for a couple of hours and was surprised at how much quicker it felt than my 3.0. On paper they're not that different but it certainly felt (whisper it) faster, more responsive, more urgent and much harder. It wasn't all sweetness and light, however, as specification was not as good and brakes were shocking...it was only 800 miles from needing a service, though. It also had a few annoying rattles and squeaks, which you really don't need as the sound of the engine howl is mesmerising! But it's still not such a stunning looking car as the Z! Just my thoughts...
