I have a 2006 with 84k.
I have two identical key fobs. The suspension sport setting noticeably firms up the ride, it's not harsh but not that sporty either, I hardly ever use it. The normal setting gives a generally comfortable ride without being too soft, comparable to the Jaguar S-Type I had before. Yes, there's a rear blind but the only time I've used it is to check it works and when giving a gizmo tour to people new to the car. I do mainly small journeys and 21-22mpg but have seen 31-32 on a long trip.
I've had the rear sticking caliper issue, both replaced at 78k. Also, an alternator problem that affected the electrics but this was fixed by an independent at low cost. Great car, can't recommend it too highly and I've owned many over the years.
