- Sun GMC in Long Island, NY, has accused GM of “discriminatory” allocations.
- Last year, the dealership was allocated just 501 vehicles from General Motors.
- GM told the dealer to buy any necessary new vehicles from its competitors.
A GMC dealership in Long Island, New York, has taken General Motors to court, alleging that the automaker told it to pull inventory from other Buick and GMC stores instead of supplying the outlet with the volume of new vehicles it says it needs to operate.
According to Sun GMC, the trouble dates back to 2018, when it began running into what it calls “discriminatory and unfair allocation.” The year before that, GM had sent the dealer 1,200 vehicles, a figure that has since been carved down by more than half. In 2023, the store received just 380 vehicles, and the two years that followed brought little relief, with 426 in 2024 and 501 in 2025.

The dealership says that, because of how few vehicles it’s allocated, GM’s quarterly reports show it has performed poorly on the Retail Sales Index. Clearing a “satisfactory” rating would have meant moving more than 900 vehicles. The store was handed 426 to work with and sold 420 of them.
Sun GMC is suing GM for $15 million, alleging that GM “has been wrongfully starving it of inventory to sell, which is causing irreparable harm and damage to Sun’s business and goodwill.” The dealer’s inventory has been as low as 50 vehicles for much of the past year, forcing it to display used cars in its showroom so it doesn’t look like the outlet is going out of business.
GM’s Non-Solution
“GM execs told me, both verbally and in writing, to source inventory from overstocked Buick and GMC dealerships despite the much higher cost,” dealership president Patrick Cassino told Auto News. He said going that route would tack on roughly $2,000 in extra cost per vehicle, a margin most dealers can’t swallow and still turn a profit.
It’s alleged that GM has violated the Automobile Dealers Day in Court Act, breach of contract, breach of the implied covenant of good faith and fair dealing, and the New York dealer law. In addition to seeking $15 million in compensatory damages, the dealer is also seeking punitive damages.
GM has not responded to the lawsuit and says it will not comment on active litigation. For now, Sun GMC is left making its case in court while its showroom floor tells the story in used metal.
