V12 Vantage vs 2-seat Strad: great question! If I had a two-seat Strad I would not swap it for a Vantage, and vice-versa. Both are tremendous but in different ways. I like the smaller dimensions of the Vantage, I love the noise it makes (secondary de-cat) and I love its ferocious acceleration. On paper it's quicker than the Strad but in real life I don't think it's relevant or noticeable. If at some point I uncork the asthmatic headers it may give me a bit more low-down twist but I couldn't imagine even that would make much of a noticeable improvement to Strad vs Vantage performance. Let's face it, if it was all about the stats then we'd not be in these cars in the first place. And if we wanted to track them we would have bought something else again. Both are a bit heavy for track-work, unless you like replacing things.
No, what these cars bring in equal but different measure is a warm glow and a huge grin. I'd have either, and love it. But I'd not swap my Vantage.
PS - Mrs Crud would swap it for Sam's four-seater, which she loves.
