I am in a pickle right now, I have ordered an '06 X5 4.8is that rolled off the assembly line on Friday and will be here on Wednesday and I have a '06 Mercedes E500 on hold that will be here on Friday. I'm trying to make up my mind, but each has advantages over the other. The X5 is lemans blue/beige/dark wood w/ nav, heated steering wheel, rear airbags, and comfort seats. The E-class is black/black and has Sat Radio, Lighting, AMG sport, Premium Packages w/ dual sunroofs, nav, adaptive seats, heated and cooled seats, 6-disc changer, auto trunk closer, and keyless go. The E55 steering wheel and spoiler are also going on it from the dealer. Both are virtually the same price, so input would be greatly appreciated.
