Yep, I looked at a handful of piccies and some video after posting my message, and I am sure it was a Grenadier.
Yes, it definitely oozed urban cool. I imagine that Kensington and Knightsbridge must be filling up with 'em.
Mind you, I do like what I saw of them in the video posted by Captain Rightfoot on this thread. Coincidentally enough (considering that I have spent very little of my life so far thinking about Grenadiers), on a professional webpage which I have just been perusing, the Grenadier popped up again. It seems that they're going on sale in Tanzania. I used to work there and not long ago there were Defenders all over the shop. Last time I was back there was early this year and it was sad to see many fewer of them than was normal not long ago.
Actually, and this may be going a little off topic, I know that at least some of the large conservation projects in Sub-Saharan Africa which have switched to Toyotas in recent years would not have done so if Defenders (I'm talking Tdi-engined jobbies here) had remained available. I wonder if the Grenadier might sneak in the back door there....
