A 996 turbo was my last "modern" sports car. It was too good, as Riviera says. It actually did get a little boring in that to have fun you have to drive too damn fast. I used it every day, which maybe added to the boredom.
I have come to love all my older cars due to the sheer sense of occasion when you drive them, and (as you know from your 308) the amazing fun you can have at legal (or at least less illegal) speeds.
When you get in the 456 (IMHO the last beautiful Ferrari 2+2) you will see that prancing horse on the wheel and when you start it you will grin from ear to ear. Worth it every time for me.
I think when you get in a modern 911, you will start it and..........depress the clutch and pull away. Your heart rate will remain unchanged.
I think the fact that you once bought a Quattroporte as a daily drive shows your true colours.
All very subjective I know, so apologies to any modern 911 lovers that I have offended.
