When Durant won the bidding, it led to the creation of the Flint Six and an attempt to create a competitor to GM called United States Motor Company.

In January 1924, the finished product was ceremoniously presented to the public as the Chrysler Six Model B-70 in the Commodore Hotel on the occasion of the New York Auto Show.

[5] The cars continued to be built almost unchanged, only the split windshield on the open models was replaced by a one-piece, top-hinged version.

There were several body style choices offered in both two-door and four door configurations, and among them was the Chrysler Touring four-door, five-passenger which was listed at US$1,395 ($24,009 in 2023 dollars [4]).

There was for the first time a trim package called Royal Coupe and Crown Sedan which in later years became model names.

The Series 60 had upgraded interior and the six-cylinder engine and upscale appearance items, and was offered in six, two-door body style choices to include roadsters with only two, four-door body style selections of a choice of convertible open or closed passenger compartment.

Standard equipment included hydraulic brakes, one-piece glass windshields, and a Delco-Remy ignition system as well as a coincidental lock on the manual transmission.

Both the Series 60 and 70 offered standard equipment wheel size of 30 in (762 mm) with a choice of wooden spoke or pressed steel discs.

The top level body style choice for the Series 70 was the Crown Sedan at US$1,795 ($31,485 in 2023 dollars [4]), offering features that were extra cost on other brands as standard.

[2] Advancements shared with the Series 62 and 72 include a taller radiator, headlight posts attached to the chassis directly, tubular front axle, rubber shock insulators on leaf springs, with throttle and headlight controls installed on the steering wheel center hub.

Convenience items included an electric gas gauge installed in the instrument panel, ignition lock on the dashboard, and an exterior mounted sun visor.

Prices listed for the Series 62 four-door, five passenger Landau Sedan was documented at US$1,235 ($21,662 in 2023 dollars [4]) on a 109 in (2,769 mm) wheelbase while the Series 72 four-door, five passenger Imperial Town Cabriolet by LeBaron was listed at US$3,595 ($63,057 in 2023 dollars [4]) on a 120.5 in (3,061 mm) wheelbase.

The ignition switch was upgraded to a keyhole, and the crown depth of the fenders over the wheels was lengthened, and built-in adjustable radiator shutters were introduced as well.

The timing was not the best with the Wall Street crash of 1929 and the Great Depression beginning in September but Chrysler forged ahead and updated their product line.

While cars of the 1930s shared common appearances across all manufacturers, some stylistic features were introduced to distinguish, and Chrysler introduced Pennon-type hood louvers on all Sixes, which was replaced mid-year with vertical hood louvers that were more functional and dissipated heat more effectively.

The front headlight tie-bar was updated to a curved appearance and the model number attached as a pendant to the top of the bar.

The Series CM introduced the new Cord L-29 influenced Chrysler corporate appearance shared with DeSoto, Dodge and Plymouth.

Engineering advances and appearances that were first introduced in 1931 on the Imperial Eight had become standard equipment on all Chryslers, to include the Series CI.

A similar car, with the same Airstream name was also sold by Chrysler's companion brand DeSoto during the period.
