Reffro's right. As far as I could detect the only difference between Darrens W12 and My V10 S8, came down to our respective driving skills - commitment - or lunacy in Darrens case
Hand on my heart I'd say the W12 had the edge in a straight line, but by a margin so slim that it would be good to try again.
The big difference is not in the handling, I think Darrens W12 has the sports suspension anyway, and I believe its an SWB too. The big difference is the sound.
The W12 is super quiet. You can hear it working (bearing in mind that Darren knows how to push it, and was), but the noise is coming from a different county to the one in which you're driving. Very deceptive, so quiet you don't realise just how the speed piles on.... until you arrive at one of those corners, in a downpour
The S8 on the other hand. I Still can't believe the way it sounded out there on the ring. I've had it for almost 12 months, but this was like a different car.
Snarling, howling and barking mad. No whooshing, no way. It's pure aggression and so totally addictive.
You have to decide what spec you want motor and hold out for that. There's S8's out there more loaded than the W12's, and I think that the basis S came with more stuff, but that may be down to them coming on the scene a few years (2006) after the W12's.
And that brings me to the main decision target. Price. S8's are still quite hard to find at sub £20k, whereas there's loads of W12's at really tempting money.
By the way. Refro's right when he says that the D2 S8 is more fun to drive. It is -
