Upside Stepside: 1989 GMC 1/2 Ton – $5,500

Jun 2020 | Classifinds, Truckin Tuesday

While the growing popularity of Chevrolet’s “Action Line” and “Square Body” pick-ups produced between 1967 and 1987 continues to grow with prices on the rise, early examples of the fourth generation GMT400 pickup that followed still remain a relative bargain.  A prime example is this 1989 GMC C1500 Sportside listed just yesterday here on Craigslist near Providence, Rhode Island with 170,000 original miles and an asking price of $5,500.  A check of the NADA Guides Classic Car Online Valuation Tool confirms this private seller has his Sportside priced on the high side of the current “Low”, “Average”, and “High” retail value range of $1,450, $3,275, and $4,725, respectively so we feel there should be some room for negotiation.  If you are serious about buying this GMC, you can start the conversation by either calling or texting Scott at (401) 480-6341 and when you do please remember to mention you saw his truck featured here on

The fourth and final generation of GMC’s C/K line of light duty trucks debuted on the new GMT 400 platform in 1988.  This is the final generation of GMC truck to feature a traditional small block V8 and carried the “Sierra” name as a trim level rather than the brand name for the truck.  This is also the generation that started differentiating between the light duty GMT400 models such as the one featured here and the heavy duty GMT800 chassis based 3/4ton and above trucks.  In our humble opinion, this is the last good looking single cab truck Chevrolet made.  The latest generation recently introduced only served to further cement our opinion.

Despite the worn clear clear coat on the front clip and the high mileage, the step side body and “too many parts to list” has wondering whether this is a diamond in the rough with a lot of potential that will likely hold, if not increase in value.  Good luck with the purchase!

Here’s the seller’s description:

“Very good shape 170,000 miles. Includes brand new gas tank, fuel pump, fuel sender, shocks, brakes, tires, calipers and wheel cylinders. New tailgate and roll pan (not installed). Winter rims with tires. B & M shifter. Too many parts to list, call for details..
