The DEC switch (the comfort/sport/etc button) isn't standard, came with a package, though it's very easy to retrofit if you follow the various guides out there. If it's a brand new engine, it'll probably last you another 100k. I'd definitely look into third party warranties (not BMW's extended) after the BMW one expires
