Analyzing over 900,000 new and used cars sold in September 2021, iSeeCars.com found that overall, the average new car takes 24.6 days to sell and the average used car takes 32.8 days to sell. Both new and used cars are selling faster than in August, where the average for new cars was 26 days to sell and the average for used cars was 34.6 days.

“The microchip shortage is showing no sign of resolution as major automakers continue to halt production, leading to lower and sometimes scarce inventory levels,” iSeeCars Executive Analyst Karl Brauer said. “Car buyers are willing to pay over MSRP for new cars and highly-elevated used car prices because they have embraced the reality that inventory shortages are here to stay for the next several months.”

The fastest-selling new car is the Subaru Crosstrek subcompact SUV, which took an average of 7.8 days to sell in September. It’s joined by a second Subaru model, the Forester in third. “Subaru’s Japanese plant, where the Crosstrek and Forester are produced, was shut down from September 7th through September 22, leading to scarce inventory for these popular models,” Brauer said.

The Chevrolet Corvette is the second-fastest seller. “Demand for the mid-engine Chevrolet Corvette has exceeded supply since its launch for the 2020 model year,” Brauer said. “Dealers stopped taking orders for the 2021 model year in March, and demand remains so high the model consistently sells for over MSRP, with an average price of $92,366 compared to its MSRP range of $59,900-$78,850.”

Ten Toyota vehicles and one from its Lexus luxury division make the list, with hybrid vehicles accounting for six models. The non-hybrid vehicles include four SUVs: the compact RAV4, the subcompact CH-R, the midsize 4Runner, and the midsize Highlander, as well as the Toyota Tacoma pickup truck. The hybrid vehicles include the Toyota Sienna minivan, the Toyota RAV4 Hybrid compact SUV, the Lexus RX 450h midsize SUV, the Toyota RAV4 Prime compact SUV, and the Toyota Corolla Hybrid compact sedan. “Toyota had its first major production cut in September, which led to a 40 percent drop in global production and reduced production of an estimated 70,000 vehicles in the United States,” Brauer said. “Hybrid vehicles have surged in popularity and have grown in sales faster than electric vehicles, and consumers have embraced the hybrid versions of Toyota’s popular cars and SUVs, leading to their rapid sales rate.”

The Cadillac Escalade full-size luxury SUV ranks seventh. “The Escalade was redesigned for 2021 to make the premium SUV even more luxurious and technologically advanced, helping it dominate the full-size SUV segment,” Brauer said. “Additionally, the popular vehicle consistently sells over MSRP and grew in sales by 123 percent in Q3 2021 over the previous year.”

Four models from the Hyundai-Kia automotive group make the list, including the Hyundai Tucson Hybrid, the Kia Seltos, the Kia Telluride, and the Kia Carnival. “The popularity of the recently released Hyundai Tucson Hybrid and the Kia Carnival confirms the public perception of Hyundai and Kia vehicles has evolved, from being budget-oriented to competing with more premium mainstream cars, and even luxury brands,” Brauer said. “Demand for the Kia Telluride has outpaced supply since its 2019 launch, and its average new car price of $45,226 exceeds its MSRP of $32,190 to $44,390.” 

Rounding out the list is the Mercedes-Benz GLS full-size luxury SUV. “Mercedes-Benz recently canceled production of V8 versions of the Mercedes-Benz GLS for the 2022 model year due to the chip shortage, which likely increased demand for the 2021 model,” said Brauer.

The average used car takes 32.8 days to sell, while the top 20 fastest-selling vehicles average 22.4 days and sell 1.3 to 2.0 times faster than the average used vehicle.

The Tesla Model 3 is the fastest-selling used vehicle for the fourth consecutive month. “The Tesla Model 3 has remained popular since its highly anticipated debut, thanks to impressive technology and performance at a relatively affordable price compared to Tesla’s earlier vehicles,” Brauer said. “A new version of the Model 3’s Standard Range Plus variant is sold out for the remainder of 2021 to further add to the already-high demand for used versions, some of which are being sold at higher prices than new versions.” An additional Tesla makes the list, the Model X. “Tesla continues to see record sales growth for its premium SUV, with the sold out Model X not being available until February of 2022, adding to the demand for  used Model Xs.”

Seven hybrid vehicles make the list: the Toyota Prius, the Honda Insight, the Toyota Highlander Hybrid, the Toyota RAV4 Hybrid, the Kia Niro, the Toyota Prius Prime, and the Honda Clarity Plug-In Hybrid. “Similar to the new car marketplace, Toyota’s hybrid and plug-in vehicles are hot sellers due to their reliability and advanced technology,” Brauer said.  “The Honda Clarity debuted in 2018, while the Honda Insight debuted in 2019, meaning most used versions are just now becoming available, and are in high-demand.”

Three sports cars and performance cars make the list, including the BMW 2 Series, the Volkswagen Golf GTI, and the Mazda MX-5 Miata. “Sports and performance cars were popular throughout the pandemic, and their popularity has continued as consumers have a heightened desire to make purchases that bring them joy,” said Brauer.

Three small SUVs make the list, including the compact Mitsubishi Outlander, the compact Mitsubishi Eclipse Cross, and the subcompact Fiat 500x. “These small SUVs do not achieve favorable reliability ratings, but likely resonate with consumers because of their affordability, with the 500x and the Eclipse cross having the lowest average used car price of all used SUVs,” Brauer said.

Two additional affordable vehicles make the list in the subcompact car category: the Mitsubishi Mirage and the Hyundai Accent.The Mitsubishi Mirage and the Hyundai Accent are two of the lowest-cost used cars on the market, and appeal to practical buyers who want low-cost transportation.”

Rounding out the list are the Kia Sedona and the Chrysler Pacifica minivans. “The Sedona is the most affordable minivan on the market, while the Pacifica has an upscale interior and a long list of standard features,” Brauer said. “Minivans have seen a bit of a resurgence thanks to more modern versions entering the new car market, and this popularity has extended to the used car marketplace.”

“As demand continues to outpace supply for new cars, consumers should act quickly if they see their desired vehicle for sale, and buyers will have to be flexible on color and trim options for in-demand models,” Brauer said.
