The Compagno used a ladder-type chassis instead of the more modern monocoque style, with torsion bar wishbone suspension at the front and semi-elliptical leaf springs for the rear axle.

The Deluxe had an Italianate dashboard, reflecting Vignale's input, complete with three-spoke Nardi steering wheel.

The engine displacement was initially kept below one liter to price the car in the lowest road tax bracket for Japanese buyers.

A Super Deluxe version of the four-door was added, while the Spider and GT gained front disc brakes.

The Consorte was initially only available as a two-door sedan, and while the Van, Truck, and Convertibles were not replaced the four-door Super Deluxe remained in production until January 1970 so as to meet existing orders.

Arriving in May 1965 in its initial 797cc form, UK press such as Autocar magazine found the car to be quite lackluster compared to its competition.

Aside from the build quality and good standard equipment, the magazine review noted its outdated styling, poor ride and brakes, high price, and a 0-60 time that was quoted as being "too slow to record."

Nonetheless, the Compagno would eventually inspire other Japanese automakers to begin exporting their products to European markets, such as the 1966 Corona from Toyota and the 1968 Sunny from Nissan (which would be known as the Datsun 1000).

According to Daihatsu, the design was aimed at "active seniors" and prioritized the relaxing comfort of the two front seats, combined with a high-quality interior.
