Singer Motors Limited was founded in 1874 as a bicycle building business out of Coventry, England -- but it wasn't until the 20th century that founder George Singer began making motorized 2-wheel, 3-wheel, and finally, 4-wheeled vehicles. Fast forward a few years, and it was taken-over and run into the ground by the Rootes Group, but not before they built a few cool cars like the 4AD Roadster. Find this 1954 Singer 4AD Roadster here on eBay bidding for $3,650 with a few days to go, located in Willoughby, OH.
