Chevrolet Canyon Pictures

The dinosaurs of GM's lineup, the Chevy S-10 small pickup and its twin, the GMC Sonoma, are dying a slow death. The duo's eventual replacements, the Chevrolet Colorado and the GMC Canyon, will roll out this fall as 2004 models.

We say "eventual" because the S-10 crew-cab pickup will still be available for another year or so. GM must want to continue milking the design that first appeared in 1981 as a 1982 model. And you thought only creaky British roadsters enjoyed such extended model lives.
