Easy, the original Boxster was even equipped with a tiny 2.5 L 204 hp engine
And stay away from the GT3 - it's worse than any other drug. One shot and you're lost forever
I agree with what has been said before - driving fun and involvement is all subjective.
What I have found while trying to better understand the differences in the P line-up is simply that there is no P-model which is able to cover all my (different) interpretations of "driving fun". I'm afraid one P-car just isn't enough
For the time being my wishlist looks like follows:
1.) Daily Driver
987S - cab fun and almost go-kart like handling in one car.
I just love it
Yes, it could use more HP, but I rarely use it on the Autobahn and on the track I actually like to be the "underdog" (better for my ego to shine in the BoxsterS than to look like a fool in a GT2)
If more comfort- and Autobahn-oriented a 997S would be the right choice.
2.) Something for the heart
An aircooled 3.2 Carrera or even SC is incredible fun to drive and these oldies wake the greatest emotions in me (finally I didn't dream of a 997 when I was a teenager)
3.) Something for the track
997 GT3/RS for sure - one really can feel that these babies are made "ready to race"
As a "hybrid" (daily driver + occasional track duty) a 997S equipped with -20mm/LSD, Shortshifter, X51 would be a good choice IMO
As I do not need the tiny rear seats, a GT3 non-CS could take that role also.
But then I'll miss the cab fun - I can deliberate as long as I want, one is just not enough
