The "logic" of the 2 seat version is that if you're not going to use the back seats anyway, why have them? Especially when it means you can then fit the carbon ones from the Enzo/MC12 in the front.
It may still be a big car, but don't be thinking its not fast and fun on a good road. Is a similarly priced 911 GT3 better as an out-and-out sports car? Yes. But would I swap my Strad for one? No.
Oh. And it's not hot in the summer. Because (a) it has working air-con and (b) the windows open. So it's not like driving a black Countach, for example.
The suspension change in the Stradale makes it much more compliant and confident over the Skyhook cars, in my opinion. I found my Stradale to be very "chuckable" on twisty roads where a Skyhook car seems to have too much hesitance while the sensors work out what it going on. It's telling that when making the Stradale, the engineers just went back to proper, normal springs and dampers.
I drove a GT3 recently actually, superb round the bends, terribly hard and crashy ride which made it not nice on a longer journey. The Stradale was no problem on long runs.
I know you know these things though, more for those that perhaps aren't fully aware.
Genuinely, anyone that says they wouldn't have a Stradale, over a GTS in particular, has never really driven one. They are more than the sum of their parts and considerably better therefore. I've also owned 2 Gransports, one heavily modified and one mint condition standard car. I love them and I do get why some would prefer them. But if you think that a GS, even and MCV is better than a Stradale, I would seriously disagree.
2 seater all the way, unless you have kids, in which case 4 seater all the way!
