In 1990, Chevrolet introduced several new features on its popular Astro van: full-time all-wheel drive, anti-lock brakes on all wheels, more cargo capacity with its greater length. The 6-cylinder Chevy Astro van has 5 seats, 3 doors, and a 4.3L engine. It's very popular among its owners, according to owner reviews. Reviewers raved about the 1990 Chevrolet Astro's engine power, towing capability, visibility, roominess, and overall reliability. They also cited the tendency of the rocker panels to rust out, and of the door locks to malfunction. The ABS system had some problems as well. The rear seats are said to be a little heavy/difficult to remove.
