That's a nice blank canvas you have there dude
I've loved space grey, at first I thought it was a tad dull but have really grown to love it and its very easy to maintain (as you will find out going from your dark porsche to your 335i!)
At least you won't baulk at how much maintenance the 335i's require having owned a porsche! (all my previous cars have been japanese and have only ever basically had oil changes, spark plugs batteries and timing belts!)
What's your plan for her?
