Early in my buying process, I was fortunate enough to visit a dealer that had a Black, Silver and GG lined up in a row. At the time I was going to go with black but seeing the GG in person really changed my mind. Black is a beauty when clean but I saw a dirty one on the street the other day and thought in looked like any other SUV. GG will maintain the good looks (I don't wash mine every week). I also like it because it's somewhat unique - almost every car is available in silver and black, very few with medium, metallic grey. I have not regretted my color choice. Good luck, you can't go wrong with any of those colors.
Thanks remery, I liked the pics and that color. I really liked the interior color. Besides my 98 silver CR-V I also own a 01 Chrysler Voyager LX in silver, it also has a similar interior color to your MDX. I'd prefer a grey/gray interior to the ebony interior or a brown in the MDX, but Honda/Acura didn't listen to my suggestions.
I believe it is time to start looking at a buyer for my 01 Silver Voyager LX so I can place my GG MDX on order!
