LaSalle was a brand of luxury automobiles manufactured and marketed as a separate brand by General Motors' Cadillac division from 1927 through 1940, created by GM chairman Alfred P. Sloan as a companion marque for Cadillac to fill the price gap between Cadillac and Buick; LaSalles were manufactured by Cadillac, priced lower than Cadillacs, shorter and marketed as the second-most prestigious marque in the GM portfolio. Built to Cadillac standards at a dedicated factory at Wyoming Road Assembly on the GM B platform with Harley Earl's styling (including a nod to the Hispano-Suiza H6 in the circled "LaS" trademark on the headlight tie bar), the 1927 Series 303 used Cadillac's "Ninety Degree V-8" of 303 cu in (5.0 L); on June 20, 1927 a LaSalle driven by Willard Rader and Gus Bell achieved 952 miles at an average 95.2 mph at the Milford Proving Grounds, the test cut short by an oil system problem. The first engine upgrade came in 1929 with the Series 328 (5.4 L), then the Series 340 in 1930 (5.6 L, 134 in wheelbase the only one used, with a radio first offered as a US$175 option; a 340 sedan listed at US$2,565 against the new Buick Series 50 at US$1,540) and the Series 345-A in 1931 (5.7 L, 134 in wheelbase), followed by the 345-B (1932) and 345-C (1933). Wheelbases were 125 and 134 in for 1927–31 and 130 and 136 in for 1932–33. LaSalle sales fell from a high of 22,691 in 1929 to a low of 3,290 in 1932. The page gives no horsepower ratings.

Owning one
We don’t estimate running costs for a car like this. What it costs depends on its condition, its specialist and how it is driven, and an average would mislead.

Photographs
By its final years this LaSalle had lost its own identity entirely, built essentially identical to the Cadillac Series 61 right before GM killed the brand.
Despite being GM's Depression-era budget-luxury line, the LaSalle paced the Indy 500 twice — in 1934 and again in 1937.
In 1927 a LaSalle ran 952 miles around a track averaging 95.2 mph with only seven minutes total spent on pit stops — nearly matching that year’s Indy 500 winning pace.
Rivals
Same body, same money, other badges — tap any card to flip.
It briefly served as senior sibling to Marquette, a GM companion brand cancelled after just one year.
Nissan hired former BMW engineers to help develop the 510's suspension, which is why period reviewers frequently compared its handling to the BMW 1600/2002.
A Trabant 601 won its class at the 1970 Monte Carlo Rally, with a second 601 right behind it in second.
The 600 was a stopgap: the P50's body over the 601's mechanicals, and for a while its estate was built alongside the new 601 saloon.
The G80 Sport brought a 370 PS twin-turbo 3.3 V6, a mesh grille and copper-tinted chrome with copper stitching to match.
The Vigor was sold only with a five-cylinder engine, an unusual configuration Honda used to fit a longer engine transversely under a short hood.
The GS/E coupe earned the nickname "German Charger" for its long hood, short deck stance borrowed from Detroit muscle cars.
This DeVille/Fleetwood was the first production car anywhere to mount its V8 sideways, Cadillac's front-drive gamble on the new C-body.
