off the line in 1996, leaving only Ford producing domestic large rear wheel drive sedans until the line was phased out in late 2011, with Chrysler reentering the market with their LX platform in 2005. Known for being durable and reliable, most B platform cars used suspensions utilizing coil springs in the front and leaf-springs in the rear until 1958, when they switched to coils in the rear; exceptions include the 1959-60 Oldsmobile 88, which used coil springs in front and multi-leaf springs in the rear. All B platform cars since 1965 have used perimeter frames with side rails, along with the 1961-64 B platform Pontiacs and Oldsmobiles. The 1958-60 Buicks and 1959-60 Oldsmobiles used a ladder-type frame while an X-frame without side rails was used on 1959-60 Pontiacs, 1959-64 Chevrolets and 1961-64 Buicks. The Rear Drive B platform was the last platform design to have the gasoline tank filler port behind the license plate after 1958. Exceptions included all station wagons, as well as all 1961-64 cars - which had the tank filler in the rear fender on the driver's side and 1965 Buicks which had their fuel filler door above the license plate. Also, the Pontiac B platform vehicles from 1941 until 1948 had the fuel filler door in the rear fender on the driver's side. This would also be the case with the B platform Oldsmobile and Buick. By 1986, the Buick LeSabre and Oldsmobile Delta 88 moved to the GM H platform. And in 1991, Chairman Robert Stempel said: He also stated that the rear drive 1992 Buick Roadmaster and Chevrolet Caprice had been produced "over my dead body." No successor for this platform was made after 1996, when the Roadmaster and Caprice ceased production. However, the Caprice would be revived and built on the Opel developed V platform for the Middle East but built by Holden, while years later the Caprice for police use along with the Impala SS successor, the Chevrolet SS, would return to America built on the GM Zeta Platform which was developed by Holden in Australia.
