I was in the market for a used 08 X5 and after looking at the pricing, it seemed a no brainer to go a few grand more and get the new 2011 X3. The new X5's are beautiful, but over priced, IMO. Besides that, they are big heavy azz pigs, so the X3 gets better mileage and is almost the same size as the older X5, so it's a win win as far as I'm concerned.
