If I was to take a flyer I'd say that the sudden lack of forthcoming Z4 info and spy pics is all part of the BMW Creative Marketing strategy. [I love conspiracy theories!

If it were my business - I'd do the same; create a fair amount of hype around conveniently snapped FEP's dressed in nightclub toilet wallpaper, dish out some tantalising tidbits of mildly ambiguous information and then pull the plug on the stream a few weeks before launch. Let the fans stew a bit in the annn..tici......pation (forgive the cheesy 70's musical cliché) and then,
wham, straight outta left field hit them with "leaked" images of the new car in all its studio-perfect glory posted by a brand new member called "Robbert_Redfid". Who, never posts again...
Luvverly - I really wish this was the truth because I'd rather not have it any other way.
