A CONVOY of treasured cars will converge on a Bradford on Avon car park on Sunday to mark the 40th birthday of a club dedicated to Austin, Morris and Wolesley 1800-type cars.

The Landcrab Owners Club was set up in honour of the new design of front-wheel drive, transverse-engine layout cars made from 1964-75.

The Austin 1800 gave the cars their nickname after a journalist, who took rally pictures from a helicopter, said the cars looked like landcrabs as they cornered sideways.

The club's Spring Meet will be held in the railway station car park where around 25 of the original cars will gather at 10am.

Sir Alex Moulton, the Bradford bicycle designer who developed the cars' hydrolastic suspension system in the 1960s, is planning to join Sunday's celebrations at 11.30am.
