Need your help. I am about to go into negotiation with a dealer in OH about a 545i with all the options I want. There is a similar optioned 545i here in town but it's an 05 and I've looked and test drove it. But the color (Orient Blue) isn't my pick. Are there any difference with 04 and 05? Below is the list of the main options:

2004 545i Met Blk on Blk.
StepTronic
Sprt Pkg
Nav
Prem Sound
Rear Sun Shade
Park Dist Control
Cold Weather Pkg

Or better yet, point me to the thread that might list the difference.
