I'm only thinking of adding the 993TT as it was the last air cooled. I just think it will hold value and give me a different driving experience being a bit more narrow and nimble. Bringing the go cart feel back to driving, but I fear that I will feel like the car is a slouch compared to my GT cars. I like Lamborghini but like you said, you can't see sh*t out the back and visibility is atrocious. Not to mention it's a bit much in the eye catching field, it does scream hey look at me a bit too much. The suspension differences you will really feel if you are pounding the car on the track, but for mountain road carving I'm ok with the MacPherson Strut.
