The 1988-1991 Buick Reatta was a luxury coupe produced by General Motors' Buick division, representing a bold departure from the brand's traditional image. Designed by the legendary Harley Earl, the Reatta's distinctive styling featured a sleek, aerodynamic profile, a sharply raked windshield, and a retractable hardtop that could transform the car from a coupe into a convertible in just 20 seconds. This innovative design was further emphasized by the use of hidden door handles and wheel covers, giving the Reatta a smooth, streamlined appearance. Beyond its distinctive aesthetics, the Reatta boasted a luxurious interior with high-quality materials, plush seating, and advanced features such as an electronic instrument panel and a Bose sound system. Power came from a 3.8-liter V6 engine, producing 170 horsepower, paired with a four-speed automatic transmission. While the Reatta was lauded for its style and luxury, it faced criticism for its high price tag and its relatively underpowered engine.

Despite its short production run, the Buick Reatta left a lasting impact on the automotive landscape. Its unique design helped to redefine the Buick brand and attracted a new generation of buyers seeking a stylish and luxurious coupe. The Reatta's innovative retractable hardtop system was a technological marvel, providing drivers with the best of both worlds: the open-air driving experience of a convertible and the weather protection of a coupe. While the Reatta's commercial success was limited, its influence on future Buick models, such as the Riviera and Park Avenue, is undeniable. Today, the Reatta is a highly sought-after collector's car, appreciated for its distinctive styling, luxurious interior, and unique retractable hardtop. The 1988-1991 Buick Reatta Service and Repair Manual is an invaluable resource for owners and enthusiasts alike, providing detailed information and instructions on maintaining, repairing, and restoring this iconic coupe.
