I think there are a few hundred in the UK
according to 'how many left' under the various descriptions as follows (not all include the word 'beta' on the registration hence the funny list)
335 beta less 87 montes = 248

32 volumex

31 lancia vx
+
15 spyder 1600

11 coupe ie
+
38
hpe

25 cpe ie

6 trevi
is that 406??? can't count that far this time of night!! anyway you get the idea
this is sorn or taxed but not any cars that have been off the road since before sorn started or ones in the hands of the motor trade
I think that's it but as you can see the descriptions are a bit quirky at dvla and it's late and I've had a glass
