The Buick Century Aeroback was part of GM’s late ’70s downsizing initiative. It featured a radical slant-back design that was intended to be innovative but ultimately confused consumers. The Aeroback’s design suggested a hatchback, but it lacked the functionality of one, leading to disappointing sales.

Despite its initial failure, it has gained a cult following among enthusiasts. The unique design and rarity of the Aeroback models have made them sought-after collectibles today. Their brief production run and distinctive styling ensure they remain a memorable part of GM’s history.

9. Cadillac Seville Bustle Back

The Cadillac Seville underwent a radical redesign in 1980, introducing the distinctive bustle-back rear end. This design choice aimed to attract younger buyers but ultimately confused many traditional Cadillac enthusiasts. The Seville shared its platform with the El Dorado and featured front-wheel drive, a significant shift for the brand.

While the bustle-back design was initially met with curiosity, sales began to decline rapidly. The unique styling, combined with reliability issues related to the engine, led to a decline in popularity. Today, the bustle-back Seville is a rare find, representing a bold but ultimately flawed design choice by Cadillac.

8. Chevrolet Corvair

The Chevrolet Corvair is often remembered for its controversial reputation, particularly due to Ralph Nader’s book, “Unsafe at Any Speed.” However, its design was groundbreaking for GM. Launched in 1960, the Corvair featured a rear-mounted, air-cooled engine, a departure from the traditional front-engine layout. This unique configuration aimed to compete with the Volkswagen Beetle, but it also led to some handling issues, particularly oversteering, which became a significant concern for drivers.

Despite its flaws, the Corvair was available in multiple body styles, including a coupe, sedan, convertible, and even a pickup. The latter was particularly unusual, featuring a side door that could lower to the ground, making it easier to load cargo. While the Corvair’s production ended in 1969, it remains a symbol of GM’s adventurous spirit during the era.

7. Chevrolet HHR

The Chevrolet HHR was GM’s attempt to capitalize on the retro design trend of the early 2000s. Launched in 2005, it was often compared to Chrysler’s PT Cruiser, which had already made waves in the market. Designed by Brian Nesbitt, who previously worked on the PT Cruiser, the HHR aimed to evoke the spirit of the 1940s Chevy Suburban.

While the HHR had a decent sales start, it struggled to maintain momentum as consumer interest in retro designs waned. The model was available in various trims, including a sporty SS version with a turbocharged engine. Despite its mixed reception, the HHR remains a unique entry in GM’s lineup, showcasing the company’s willingness to experiment with design.

6. GMC Envoy XUV

The GMC Envoy XUV was an ambitious attempt to innovate within the SUV market. Introduced in the early 2000s, it featured a unique sliding retractable roof that allowed for a versatile cargo area. However, this design added weight and complexity, negatively impacting handling.

The Envoy XUV was only produced for two years, with limited sales numbers. Its unusual design and features have made it a rare find today, representing GM’s willingness to experiment with SUV designs during a time of significant market change.

5. Fourth Generation Chevy Caprice

The Chevy Caprice of the fourth generation took a bold risk with its design, moving away from the traditional square shape of its predecessors. Launched in the early ’90s, the Caprice’s new look was polarizing, with many likening it to a whale. Despite this, it managed to sell over 100,000 units annually for several years, primarily to police and taxi fleets.

The Caprice’s unique design and large size made it a standout in the market, but it ultimately fell victim to changing consumer preferences as SUVs gained popularity. Today, the Caprice is remembered as a symbol of GM’s willingness to take risks in design, even if it didn’t always pay off.

4. Pontiac Aztek

No list of weird cars would be complete without the Pontiac Aztek. Launched in 2000, the Aztek was infamous for its unconventional styling, which many considered unattractive. Despite its polarizing design, the Aztek was packed with practical features, including a built-in cooler and a tent attachment for outdoor enthusiasts.

While the Aztek struggled with sales during its production run, it has since gained a cult following, particularly after its appearance in the TV show “Breaking Bad.” The Aztek’s unique design and features have made it a symbol of automotive eccentricity, proving that beauty is often in the eye of the beholder.

3. Chevrolet SSR

The Chevrolet SSR was GM’s modern take on the classic pickup truck, inspired by designs from the 1930s. Launched in 2003, the SSR featured a convertible top and a unique design that combined elements of a truck and a sports car. However, its unconventional styling and lack of practicality led to mixed reviews.

Despite its quirky appeal, the SSR struggled to find a market. The vehicle’s weight and underpowered engine hampered its performance, leading to disappointing sales. Nevertheless, the SSR has garnered a dedicated fan base, and its rarity has made it a collectible item among car enthusiasts.

2. GM EV1

The GM EV1 is often hailed as a pioneer in electric vehicles. Launched in 1996, it was the first electric car produced by a major automaker and was available for lease only in select markets. The EV1 was based on the Impact concept car and featured advanced technology for its time, including a sleek design and impressive range.

However, despite its innovative features, GM never intended to sell the EV1 outright, opting instead for a leasing model. The car’s production ended in 1999, and many units were destroyed, leading to significant backlash from environmentalists and car enthusiasts alike. The EV1’s legacy lives on as a symbol of what could have been in the electric vehicle market.

1. Dustbuster Vans

The Dustbuster Vans were GM’s response to the minivan craze of the 1980s. Featuring a futuristic design and plastic panels, these vans were unlike anything else on the market. However, their unconventional appearance and limited functionality led to mixed reviews from consumers.

Despite their initial failure, the Dustbuster Vans have become a nostalgic symbol of the era. Their unique design and innovative features, such as a spacious interior and sliding doors, have made them a memorable part of GM’s history, even if they didn’t achieve commercial success.
