Haha....I have the 2018 Cayman AND the "clapped out British sports cars."
My garage is like the
ridiculous to the sublime
Also, don't give up an performance driving yet!
You own a Porsche, which is a great tool to exercise your driving skills. Your local Porsche club probably has track days / DE days / autocross events. These can be great fun!
I'm in my late 60s and am signed up for at least 8 weekends of (vintage) racing with my old MG in 2018.
Plus probably some Porsche DE days with the Cayman.
At least half the guys I race with are older than me and one of the guys I have the most fun racing against is 80.
Roger Penske never calls any of us anymore, but we still have a great time.
