This 1989 GMC Sierra C1500 Step-side is the best truck I have ever owned. It beats owning any Ford Ranger.
This was originally a Michigan truck, but I bought it off of eBay in 2000 from a dealer in Florida.
The truck still bears the original two-tone maroon/silver paint, and it shines like a new vehicle.
The interior is original and is still in immaculate shape.
The cloth bench seat in this truck is the most comfortable I have ever sat on. I definitely prefer it over any bucket seat.
It seems to me that the original owner of this truck neglected the drivetrain.
Gas mileage and oil consumption were high when I bought it, but with a little TLC and some new parts, I have minimal oil consumption and the gas mileage up. The best gas mileage I have gotten is 17 in the city and 21 on the highway (in the summer)!
The truck is very quick with its 210 horsepower 350.
However, the step-side bed allows for very little cargo. A full bed will drop the gas mileage to 18 (at best) on the highway.
This is an all-stock truck, and it has proved to be "Professional Grade."
My next truck will definitely be another GMC (either a Z-71 or a diesel).
No more headaches with Fords or Silverados again!!!
