Mate of mine spotted one in Lower Earley (near Reading) mid last week. Said it was a monstrosity (he drives an E39 Alpina B10 4.6 so isn't a BMW hater).
There is a red/orange (probably has some special BMW name for the colour!) X6 that I've seen in Norwich a few times. In the flesh its a big car/4x4/thing and looks pretty awkward in my opinion!
Yeah this car is on loan from the factory to BMW UK, should be the dark red colour Vermilion Red, left hooker with German plates
Spotted it just down the road from off junc 11 on the M4 a few weeks ago, waved at the guy...nowt back...probably thinking who the hell was that loon!!
but it was BIG!
