You're so right, I've been watching Saxton4x4's Mini page and they've sold quite a few ICE Mini JCW's in the past 6 weeks. Miss my car like crazy! I'm getting around on an ebike but I miss my creature comforts like a heated seat and lumber support backrest, as well as the thumping HK speakers.
Unfortunately, the reason I had to sell was because I didn't want to drive 2 different Mini EV's with a vast difference in range, got the 2024 Cooper SE Sport on a lease but the factory order won't be delivered until Oct 2024

Which means no summer fun and long road trips. I really hope the acceleration lift in sport mode is the same as my previous Mini EV, so addictive!!!!!!!
Your car looks even better in silver! You could do a road legal version of the Mini Pacesetter

If you ever think about doing the rear JCW on your car, I've got 2 JCW LCI2 rear bumpers for sale, a red one and a midnight black. Very cheap to respray to silver.
Basically, the shutters remain open when the car is turned on and not moving, it only activates when you drive 20mph+. This video should help you understand better
