06 = better deal, + u get Xenon lights with it

 

the 545i would be WAAAAAYYYYY more fun to drive! if i had a chance to do it again, i'd do the 545i or 550i.. i bought mine and purposely did not test drive the 545i or the 550i,(i was trying to be practical) then my sister "one up'd" me and got the 550i.... DAMN that sh!t is soo powerful! i wish i never got behind the wheel of her car! that's okay... mine looks better! all show, no go!!

 

+1 for the 06

 

If you have to get one of these cars.. then get the 06.


I would look for a deal on a 530i. They're out there for good prices you just have search.
