1977 GMC Pickup Sierra Grande 15
It has the durability missing from the new GM trucks
The truck had leaking valve cover gaskets and needed a tune up when I bought it.
The radiator was leaking and was cheaper to replace it than repair it. At that time I replaced the hoses, thermostat, and water pump.
The starter and alternator have been replaced as well as the battery and cables.
Everything else has been routine maintenance.
This truck was made to work. I once hauled seven engines in the back for a friend and the truck was as powerful as when it was empty. I have driven on many rough roads and the truck still rides and drives good.
These trucks have one problem though. Rust. The door hinges are rusting out, but I found a pair of doors from a later (80's) model truck with no rust for $50.
GM has had many quality control issues with their current trucks and would do better producing these again. This truck has never let me down once.
Would you buy another car from this manufacturer? Yes

I have owned the 1977 GM 3/4 ton Sierra for 6 years. I have done routine maintenance: Tune-ups, oil changes and chassis lube. I added over-load springs and changed the carburetor to an Edelbrock direct replacement from a Holley, because of a CA smog potential issue.
It runs very good with the new carb, and I can smoke the rear tires. But the Holley carb seemed to be more to my liking.
At first, on start-up, the exhaust would produce grey smoke until it warmed up. I changed to a heavier grade oil along with an oil conditioner, and that cleared-up the problem. I tightened the valve covers and I have not had an oil leak in 6 years.
I have recently driven it from Northern CA to Southern CA without any problems. I like that it has a high capacity for loads and towing. I know there is no escaping the physics of energy consumption under heavy loads, i.e. 12 MPG. I am willing to pay this price for the reliability and availability of said energy.
I will eventually restore this truck and hand it down to my kid.

GM does not have the courage to build real trucks anymore. Shame!
