This 1940 Buick Series 50 Super Convertible was customized and modified in 2014, reportedly at a cost of over $100k. The original frame and suspension was replaced with a Lator Gator USA custom chassis with Corvette C4-based suspension, and it rides on Strange Engineering adjustable coilovers with 16″ Dayton knock-off wire wheels mounted over disc brakes at each corner. Power comes from a GM Performance 6.2-liter LS3 V8 linked to a GM 4L65E automatic transmission. Inside, the car has a custom two-tone upholstery, diamond-stitched seats, Vintage Air climate control, and a modern stereo. The custom dashboard has New Vintage Woodward gauges and a one-off ignition dial with a push-button starter. In preparation for the sale the BFGoodrich whitewall tires were installed, Russell Performance braided front brake hoses were installed, and the accessory belt and fluids were changed. This Series 50 Super is now offered by the seller in New York on behalf of its owner with service records and transferable registration.

The body was stripped and repainted by a previous owner. The current owner replaced the power-operated dark red top at the same time the interior was customized and installed. LED lights were installed along with a shaved door handle popper kit. The doors and trunk are key fob operated as well. The seller notes chips and imperfections in the paint, a blemish in the hood, and pitting in the chrome.

The car rides on a Corvette C4-based independent suspension with adjustable Strange Engineering coilovers and disc brakes at each corner. The 225/60 BFGoodrich whitewall tires were mounted on the 16″ Dayton knock-off wire wheels in preparation for the sale, and Russell Performance braided front brake hoses were fitted. The car is also equipped with power rack-and-pinion steering, a Hydratech Hydroboost system, and a chrome dual-reservoir master cylinder.

The cabin houses front and rear bench seats with diamond-stitched upholstery, two-tone door panels, and bound carpeting. A Vintage Air climate-control system has been added along with an Alpine stereo with USB port and Sirius Radio connectivity. Speakers are mounted in the doors, and a subwoofer is mounted in the trunk. Dynamat insulation was fitted under the carpeting, and the dashboard was painted red to match the body.

New Vintage Woodward gauges and a Grant steering wheel were also fitted. The 950 miles indicated represents the distance driven since the build was completed, with total chassis mileage unknown.

The engine is a GM Performance 6.2-liter LS3 crate that was installed along with an engine module kit, stainless-steel fuel lines, an electric fuel pump, and a stainless-steel exhaust system with MagnaFlow mufflers. A GM Performance ECU handles engine management. The accessory belt and oil were changed in preparation for the sale.

Per the seller, the transmission is a GM Performance 4L65E automatic.

A spreadsheet of the work performed is detailed in the gallery along with images of the work in progress.

The car is registered as a 1940 Buick using VIN 13850997. The transferable New York registration acts as the ownership document.
