Actually, what I think you might find is that BMW has two or three trim packages that the Cadillac may list as individual options. There weren't a lot of individual options on the BMW.
Putting aside color combos though...
- Sunroof, which both have upgrade options on
- Entertainment systems, which both have upgrade options on
- Wheel packages, which both have upgrade options on
- Brake caliper trim/color options, which both had an upgrade on
and a few others I'm probably forgetting. Now one could go back and nickel and dime each additional feature and argue which has what and which doesn't, but you're not slumming it in either, at the end of the day I went and drug each car through the available option "garden" that each had available and those prices what I come up with. It's not like I picked and chose things to my liking. I said "CMNT is a baller and I want it all...!"
Yes, BMW had an optional set of choices for the faux carbon fiber dash treatment the Cadillac doesn't. But the Cadillac has a dizzying amount of Bluetooth options, cargo options, and other things. 6 of one, half dozen of the other...
