Even though I'm not new to X5World/XOutpost as a member I am new to the X5 (or at least hope to be.) I've been eyeballing the 4.6 and 4.8is for quite sometime and am finally ready to pull the trigger. So I wanted to get some of the members advice. What after market accessories are you guys seeing, and does anyone know what the button/lights to the left of the Nav might be? Questioned the dealer but have yet to hear back.

Originally I wanted silver but finding one with the alcantra leather sport seats seems to be a bit harder than I expected (of course I just started looking last firday so I may be being a bit impatient.)
Should I wait for the perfect one or am I being too picky when it comes down to seats, interior trim, load floor and exterior color? And on that note how do you guys like the sliding load floor, should it be a deal breaker or is it just a cool option?

Anyway here's a link to the 05 4.8is

I personlly think the asking price is a bit high when compared to the NADA clean retail value so I'd definitely be offering lower especially since I'd be traveling to get it. Thanks for your comments as I really love this forum, I don't even own an X yet and I've read almost every section.
