Thanks for all the great responses!! You guys have been very helpful!
I looked around and because of the situation with the dealer taking my defective 550i on trade I had to make a decision...and I did!
I kept the Bronze for an afternoon and the color just didn't feel right....don't get me wrong...it's a good looking X5...just not my preference. The Alpine White really spoke to me.
The Bronze had the lumbar support but not the comfort seats which really wasn't a big step up. I already own the ipod integration kit so the USB option didn't matter either. The comfort access (which I currently have on my 550) will be missed but not a deal breaker. The only thing I'll miss will be the Logic 7 sound system and the sport package suspension.
I'm taking delivery of the white X5 on Monday fitted with a brand new set of black 215's in 21" with Dunlop tires. I was hesitant on the black rims but the dealer had a last set left over and they gave me a sweet deal on the wheels so I couldn't say no. Ultimately, I would of gone with a set of silver 214's in 20" but I think the black 215's in 21" will look pretty cool. They had an Alpine White M3 with black rims and the combo looked pretty good.
Do you guys think the lack of sport suspension will be an issue with the 21" rims in terms of drive or look?
I'll post some pics as soon as I get it!
