Only you can decide on the grey, it's a personal decision. Me and the wife pondered over Reflex Silver, Steel Grey and utlimately Carbon Grey. We were going to change our original Reflex Silver order to Steel Grey and went to the showroom to have a look at it on a std Mk6. It was a bit lifeless for me, so we changed to Carbon Grey instead. Haven't seen Carbon Grey in the flesh, but it looks good in pics we've seen.
But ultimately it's not what others think, it's down to you and what you like
