Re: Can you turn P4 into 2WD?
Re: the interior: I'm not a fan of sud/sprint/33 seats, which I see as being all pretty similar. The P4 has a recaro interior and the seats look to be a fair bit more supportive and comfortable. Having said that, I've not sat in a regular 16V's seats so maybe I'm talking complete rubbish.
I've only spoken to one bloke here in Tasmania about the P4. He's an Alfa mechanic and races a GTV6 occasionaly and he referred to it as a bit too heavy compared with the 2WD version and therefore a bit slower.
I'm still quite keen on it, though - whether it be in 4 or 2WD format. The interior and the slightly more aggressive stance alone are worthwhile.
