I see mine most days!.
I went to a CAR Summer run to Duxford recently and there were 6 there- including 4 from around here (Cambridge) and two owners who had left their A610's at home. So much for exclusivity of A610's around here but I've not seen another one on the road apart from that (or a GTA for that matter except at the ACE).
I agree with Stephen, when I joined CAR Tim gave me a call. He seems to know most of the UK ones from memoryand will be able to give you a definitive figure. The stats then were (from memory) 55 imported (of the 68 RHD made), 35 in the club (CAR) about 45-50 known to Tim. .
Here is are some shots from the CAR day (if I have got this editor right). Funny how the Clio V6 looks huge compared to the Alpines.
If you come up with a figure (apart from the 3? DG has got) I'd like to know.
Thanks
Lee
