We test drove both seats and initially felt that the standard ones would be a better choice. But, reality has a way of intruding on one's plans. I found a "used" Stelvio Ti Sport with 1700 miles on it and paid about $15K under MSRP for it. It has the Ti sport seats. I bought the car in Las Vegas and immediately drove it 1100 miles home to Oregon. I think the sport seats will do nicely. I'm 6'0", 200lbs with long legs. The adjustable side bolsters fit my bulk pretty well, and the lumbar support is better than ones I've had in the past. I also wish the seat bottom could be raised and lowered in front as well as in back, but the thigh extension might help in that regard - I haven't used it yet.
btw, it's a Ti Sport without a sunroof. So they do exist.:wink
(I also want to add that these seats, while pretty nice, are not as good as the ones in my beloved '85 Peugeot 505 Turbo. I still miss that car. It had the Best. Seats. Ever.)
