$5800 is a lot of change, but you do get a lot for the money. Extended merino leather is an expensive option on the other models that offer it. Individual trim is worth $1080 if you want it or zero if you're just as happy with standard trim. The headliner isn't just black, it's alcantara. I saw a photo the other day and it is much different from the normal black headliner.
Like you I prefer the look of the standard bumper, and the individual wheels look very good with this bumper. Here's a clip that shows the wheels on an individual touring:
The clip also shows satin aluminum exterior trim which isn't available in the US without individual.
I've been considering ordering individual on my car, but I don't expect it to help the car's resale value. Buyers who like this sort of thing usually want a new car.
