Vehicle Description

The 1970 Buick GS represents the pinnacle of Buick performance during the muscle car era. Once General Motors lifted the ban on greater than 400 cubic inch displacement engines in mid-sized models Buick was quick to build a 455 cubic inch motor for the Gran Sport line.

This 1970 Buick GS 455 Convertible has been well maintained and upgraded, as necessary. This GS is finished in its correct color scheme of Silver Mist Metallic exterior with a black vinyl interior and black cloth power top.

Although not a number's matching motor, the motor was rebuilt in 2016 with a correct 455 cubic inch motor as identified by the casting #1231738.

This 1970 Buick GS 455 has such features as upgraded Wilwood 4-wheel power disc brakes with hydro boost, power steering and power convertible top. The top is free of any imperfections and operates effortlessly.

The black interior shows well with newer carpets and dash gauge cluster. The full-length center console with woodgrain houses the horseshoe shifter which is mated to a TH400 automatic transmission.

The underside floors and frame of this Buick GS 455 are very solid with no areas of corrosion shown.

Pump the gas turn the key and you awaken the giant under the hood. This smooth-running powerful motor with endless torque sends this Buick down the road without effort. With the upgraded braking system, it will come to a halt just as quick.

This 1970 GS 400 Convertible should not be desired by just a Buick enthusiast but by any true muscle car enthusiast.
