Is there a motor vehicle called a Bristol?

A couple. Bristol is an auto manufacturer in the UK. There was also an aircraft manufacturing company called the Bristol Aeroplane Company (which was split and merged into BAC and Hawker-Siddley). There was also Bristol Commercial Vehicles, which was merged into Leyland and closed down in 1983. Leyland was later bought out by PACCAR, Inc. (who also own Peterbilt, Kenworth, and DAF), and the marque was later retired by PACCAR.
