Review of the 2003 GMC Sonoma

  • We know the value of an old trusty pickup, but in the Sonoma's case, it's just plain old. A redesign is on the way next year, but if you need a compact truck now, we suggest checking out the competition first.

  • Safety
  • Pros

    Multiple configurations, fuel-efficient base engine, torquey V6.

  • Cons

    Low-buck interior, spotty build quality, poor resale value.

  • What's New for 2003

    The Sonoma gets a few changes for what will be the final year of production of the current model. There's a new split-folding bench seat on all two-wheel-drive models, new seat materials, an optional six-disc CD changer and a sport package for crew-cab models.
