The Willys Aero was a line of passenger cars manufactured first by Willys-Overland and later by Kaiser-Willys Corporation from 1952 through 1955 in the United States of America.

1955 saw two new models, the two- and four-door Ace sedans (renamed Custom shortly into the production run) and two-door hardtop Bermuda.

Floyd Clymer noted the car was quite capable of comfortably cruising at highway speeds of 80–90 miles per hour.

There were some of each model that were re-serialed 1953s with 1954 trim hung on them and then there was the regular run in which some of the Aces and Eagles received the Kaiser Super-Hurricane engine.

On the regular run, all Aeros received wraparound one piece windshields and rear windows and a new instrument panel, even the Lark.

All 1954s received larger taillights, "hooded" headlight and parking light bezels, and different bumper guards.

[3] A 1979 newspaper article in the Toledo Blade commented on an Aero-Lark DeLuxe on a 3,500 mile tour of America, noting that it would make "a perfect 1979 model, with 108-inch wheelbase, all-welded unit body, and 28 mpg combination city and highway.
