has this:
1991: A more powerful, high-output V6 became available in 2WD models during '91. All outboard seats now had lap/shoulder belts.
1992: Still another high-output engine joined the Astro option list. This one developed 200 horsepower. A new "Dutch" rear-door option featured a one-piece glass liftgate with separately opening split panel doors below.
1993: Astro's 4-speed automatic transmission gained electronic shift controls, plus a second-gear start feature for improved slippery-surface traction. The base engine gained 15 horsepower, and speedometers now were calibrated to 100 mph instead of 85.
1994: The driver-side airbag became standard in all Astros. Side-door guard beams went into front doors and the sliding side door, while a center high-mounted stoplamp was installed in the roof.
1995: Facelifted with a new grille and nose for 1995, all models now came with extended bodies and a 190-horsepower engine. CL and LT option groups featured new composite headlamps and body-colored fascias.
1996: A passenger-side airbag went into Astros for 1996, along with a new dashboard that contained rotary controls and a locking glovebox. Horsepower remained at 190 but torque dropped by ten pound-feet, peaking at lower rpm than before. New spark plugs were said to last 100,000 miles. A new engine cover increased front foot room and contained molded-in cupholders.
1997: Speed-sensitive power steering and daytime running lights went into the '97 Astro. Optional leather upholstery became available later in the model year.
1998: Astro gets only exterior color changes and a revised transmission for '98.
1999: Astro's all-wheel-drive system was revised so that power was only sent to the front wheels when needed for maximum traction. Other changes included a standard overhead console on LS and LT trimmed models.
2000: Eight-passenger seating became standard this year, so no more 5-passenger models were available. A 7-passenger setup with two second-row buckets remained as an option. Chevrolet claimed that internal changes made the Astro's engine quieter and smoother for 2000. A Tow/Haul mode was added for more-efficient shifting when carrying heavy loads. New standard features included headlamps that switch on automatically in low-light conditions, a larger fuel tank made of plastic instead of metal, and retained accessory power that permits operating electrical accessories for up to 20 minutes after shutting off the ignition.
2001: A tilt steering wheel, cruise control, CD player, remote keyless entry, and power windows, mirrors and locks were newly standard in 2001.
2002: Cargo models offered remote keyless entry and a rear heater for 2002.
2003: The standard antilock brakes are upgraded to an all-disc setup and wheels are increased by one inch to 16-inches on all models.
2004: There were no significant changes made in 04.
2005: There were no significant changes made in 05.
