Passengers entered through a single, large, common door. A flexible seating system could be easily reconfigured (except for the driver's seat, which was fixed). The designer anticipated the seating in modern minivans, such as the Chrysler Voyager and Renault Espace; a small card table could be fitted with the passenger seats as needed. Interiors were appointed in leather, chrome, and wood. Design elements also worked in a stylized ancient Egyptian scarab motif, including the car's emblem. Visibility to the front and sides was similar to that of an observation car, although rearward vision was negligible and there were no rear-view mirrors. The innovations did not end with the car's layout and body design. In an era where almost everything on the road had rigid axles with leaf springs, the Scarab featured independent suspension using coil springs on all four corners, providing a smoother, quieter ride. The rear-engine-induced weight bias coupled to the coil spring suspension and "Oil Shock Absorbers" endowed the Scarab with "Smooth Riding and Easy Steering on Rough Roads", if not very good handling and traction. The rear swing axle suspension with long coil spring struts was inspired by aircraft landing gear. The Scarab suspension inspired the later Chapman strut used by Lotus from their Lotus Twelve model of 1957. The Ford flathead V8 drove the rear wheels via a custom Stout-built three-speed manual transaxle. The engine was reversed from its normal position, mounted directly over the rear axle and with the flywheel and clutch facing forward. The transmission was mounted ahead of this, reversing and lowering the driveline back to the axle. This unusual layout would later be repeated by the Lamborghini Countach. A drivable prototype of the Scarab was completed in 1932, probably the first car to have an aluminum spaceframe unit-construction body. Some frame parts were steel. The second prototype was ready in 1935, with some styling and mechanical changes. The headlamps were set behind a fine, vertical-bar grille, and at the rear, narrow chrome bars curved from the back window down to the bumper, giving the car its Art Deco appearance. The body was changed to steel to reduce cost. Stout stated that the car would be manufactured in limited quantities and sold by invitation. Up to a hundred a year were to be made in a small factory at the corner of Scott Street and Telegraph Road (US 24), Dearborn, Michigan. Although the Scarab garnered much press coverage, at $5,000 (equivalent to $80,000 in 2010), when a luxurious and ultra-modern Chrysler Imperial Airflow cost just $1,345, very few could pay the hefty premium for innovation.
