Archive footage of the Bronco in action can be seen on Flickr at this location.
The Llwyngwril Systems Bronco was a relatively successful off-road vehicle. It was known as the "Bucking" (or other rhyming epithets) Bronco to its drivers, who generally had strong stomachs.
Sadly the Bronco was replaced after a short service life by conventional 4x4 vehicles. The Bronco was let down by its payload of just the driver, lack of steering, lack of mudguards and by being too silly.
