GM’s sales have been solid. However, even GM has some duds dealers want to move.

A new study by reveals that three GM models, in particular, are among the slowest to sell new vehicles in America. They include the Buick Encore, the Chevy Impala, and the Cadillac Escalade ESV.

The study by looked at over 4.4 million vehicle transactions from March through June 2020. found that the average new car takes 96.9 days to sell compared to 57.8 days during the pre-COVID timeframe of November 2019 through February 2020 (from analysis of another set of 4.8 million new and used cars).

“The effective demand for these vehicles has slowed in the wake of the COVID-19 pandemic due to lockdowns and downturns in the economy, but the change was much more dramatic for new vehicles than for used vehicles,” said iSeeCars CEO Phong Ly.

Interestingly, the vehicles are all different. The subcompact premium Encore makes the list, as does the aminstream large sedan the Impala (now discontinued). The legendary Escalade ESV, arguably GM’s flagship vehicle is also growing moss on dealer back lots.

iSeeCars’ CEo Phon Ly mentioned why the Encore may be on the list, saying, “Given the popularity of the Buick Encore GX, which is among the fastest sellers, it suggests that consumers are favoring the Encore GX and buying it instead of the Encore.”

Buyers know that slow-moving vehicles often translate to deals at dealerships. If an Encore, Impala or Escalade ESV have been on your wish list, now may be the time to shop.
