It's enough to make Del Boy weep into his sheepskin – there is only ONE Reliant Robin left on Britain's roads.
Only one Robin is licensed for use on the road – and only one Reliant Fox, too.
There is only one remaining Moskvitch 408, one Talbot Tagora, and one Datsun 200.
Not all of the rarest cars in Britain are mass-produced relics of the 1970s and 1980s, however.
You are also highly unlikely to see a Lexus LFA or Koenigsegg supercar, as only one of each is licensed for British roads, too.
Some of the cars on the 'only one in Britain' list are veritable classics.
They include the Maserati 425 and the Aston Martin DB1 – the original sports car produced by the British firm from 1948 to 1950.
Others were experiments that didn't exactly catch on.
There is only one Mia L3, for example – an electric car made before electric cars became, well, good.
There is also just one licensed Piaggo Ape, a three-wheeled commercial vehicle apparently more at home in the winding hills of Tuscany than on the B6343 to Morpeth.
While in general the list is a walk down automotive memory lane, some of the entries are a little more disturbing.
For example, someone somewhere in Britain has licensed a Pinzgauer armoured car to use on the roads. Great for escaping hostile fire, no doubt, but probably not one to use on the school run or weekly trip to Tesco.
