What Edmunds Says

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.

Pros

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

Cons

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