1990 Oldsmobile Expression
The Expression looked like a futuristic family wagon but was packed with tech usually seen in luxury sedans. It had rain-sensing wipers, a built-in CD-ROM navigation system, rear-seat TV screens, and even a built-in vacuum cleaner. Seriously. It also used a hybrid drivetrain and plastic body panels.
While it was never meant to be sold, many of its features foreshadowed minivan and crossover tech that would become common years later. Think of it as a 1990s preview of a modern Lexus RX.
