Really great read of your journey through the ranges and how decisions were came to be made.
Cannot fault your thought process based on circumstances even letting the R go due to practicalities, though now have the R expect to keep it completely as main car and then 2nd car that's how much love it.
My review of my 3 years with the GTD was its all the car you would ever need, you get everything would seek across the board.
However, when you drive and R or a clubsport imagine, you understand what the GTD misses, these cars (obviously) add that layer of something, that je ne sais quoi, some soul and are really the cars in this range that you would want, not need.
Personally love the clubsport, yours looks awesome right there, and totally get it and given how presented itself to you, the journey, then I would call that fate and hope you enjoy the feeling it gives you for many years (and give the long suffering wife a break from your wheeling and dealing
)
