Whether it was genuine or a replica, I'm not sure, but if it was a real one, then it is a very rare car. Spotted saturday morning on the M5.

Truly a rare beast...a great car that provides more fun with 40 odd bhp than many cars do with 10 times that amount.

I have seen a company advertising replicas and parts to get to the Arbarth spec. I am having problems checking (explorer wont open another window at the moment) but it could be Middle Barton Motors.
