Thanks rayaans, I knew you'd have checked them out!. Knowing how the journo's don't like anything non German I'd noted their comments but taken with a pinch of salt, but you seem to confirm it. It is the additional power that grabs me, and that there are even fewer on the road than Lexi. You make a good point about the 450h, I have driven one of them and yikes it's fast, but also too big really. if the Q50 is the same size and mpg is that bad I'll pass. Nearest dealer is 50 miles away as opposed to 3 for the Lexus, but price wise they seem keen. That said I find the configurators impossibly infuriating and think I'll take a wander down to Maidstone and see what I think in the flesh.
Nice to have something other than a Lexus to research though.
