I've not owned a properly fast car before (had a couple of large engines eg: Opal Monza with the 3 litre straight six), but just recently I hired this for a tour of Scotland:
(yes - the 5.0 litre V8 model)
Really fun car to drive! Seriously comfortable, the cabin is pretty spacious, the seats very comfortable: not just heated, but air-conditioned too! Also has an excellent B&O sound system. Wafts along very nicely indeed.
However it has some issues that flaw it for anything other than 'normal' road driving (imvho). The largest of which is that if you're wafting along and come across a slower vehicle, passing it is either a case of fiddling with the setting to put it into 'Sport' mode, where it becomes difficult to drive, always hunting for gears, or waiting for a seriously long gap (we're talking 200yards+) which will allow the gear box enough time to drop 4 or 5 gears (there's 10 in there) when you floor it.
Overtaking is a case of :
"Here's a gap, is it long enough.... hmm - I can't even see the end of the straight in over the horizon, it might be long enough, I'll risk it!
"Pulling out and: FLOOR IT"
"ok, I'm waiting, the gear indicator's gone blank, which one is it going to pick this time?"
"Ok, starting to get worrie... "
ROOAAAARRRRRRRRR
"HOLY SHEEEEET"
I very nearly had a nasty experience because the down change takes so long and an overtake that the Rockster would have handled with panache took about 3 times as long as it should have done.
Playing with the flappy paddles didn't really help either, there's so many gears in the box that for regular driving it's simply easier to leave the auto to do it's thing.
The other issue with it being a GT car is the range: 50 litres of unleaded gets you around 400 miles, if you're relatively gentle, so you're constantly watching the range indicator and (in scotland), wondering where the next open petrol station is.
Huge amount of fun though, the engine noise (partially piped into the cabin) is massively addictive, and yes I couldn't help showing off the 'squat' when I spotted a couple of likely lads in an old A6 giving it the eye when I passed them on the A1.
Very very nice to drive with the top down too, even at motorway speeds, I was impressed at how little wind got into the cabin.
Would I buy one? Only if I'd won the lottery - it's too thirsty and the gearbox would drive me insane. But it's definitely got me thinking about drop-tops and V8s. (and yes, I'm hoping like hell I haven't tripped any cameras while up there).
For reference - I hired it from these guys:

) in my old Beemer which is worth all of about £4.5k lol, he looked a bit shocked at about a ton when he looked left and saw my grinning face still next to him
