I'd own the car that's the most fun to drive.
For me, it's the one with the most driver involvement. One that puts a smile on my face every time I get on the throttle or take a turn even half way to the limit.
So I'd have to test drive both.
Since you're so convinced the Turbo S is better Louis, I assume you've driven both. Oh wait, you haven't.
So you're just basing your decision on magazine figures and your irrational bias...
Suck on your stupidity; you'll never run out.
