Back to the 20's or 30's for todays spot within 5 minutes of each other, a pair of open-top green Bentleys in Northumberland...must be something on.
They are easy id's because there are so few of them, and any that do exist and are active, photographed regularly, and highly likely to be in the Owner's Club, or a Vintage Sports Car Club, or take part in vintage rallies.
So despite not having my camera to hand, here's the very vehicle I saw today. Bentley 1924 3-Litre.
Now the other one I have forgotten the reg for...but it looked pretty much the same!
