This is my second GMC. Best vehicle I've ever owned. Extremely reliable and efficient. Steering is straight. No brake surging. Drive train remains like new. Doesn't use or leak one drop of oil, or any other fluids. Excellent cornering without sway. Quiet interior. 4 wheel drive works flawlessly and smoothly. I will never buy a Ford again.

My 98 Sierra SLT runs excellent. The truck has 227 thousand miles on it. Let me preferance what what im going to say next. I am talking about my truck and not all GMC Sierra's. So here are the words im using to describe it. It's been a dependable, excellent running,comfortable,stylish truck .The only negative i found was it's difficult to work on Things that the average joe should be able to do are hampered by covers or hidden and that can be annoying. That aside, properly maintained, they will go forever. joe caprio

When I got this truck,I realized I needed more power and fuel economy. So I surfed the web for these products,then bought them and installed them easily.I now get 19-20 MPG HWY and 17-18 City for around $700. The wear out quick items are A/C compressor and alt..I just changed these out at 65000- 68000 miles.Thats why I bought an extended warranty.

I have really enjoyed my 98 GMC pickup..I drive it hard and it performs well..have tinkered with it a little to boost performance and it made a world of difference...open up the exhaust and air intakes and the truck responds very well..
21 years old. Now 25 years old.

I bought my 1998 GMC Sierra new. At 212,000 miles the 305 CI V8 mushroomed a valve, as they were prone to do. I decided to put a more robust 350 CI small block V8 that made a HUGE difference. It has a 5-speed standard transmission with a manual transfer case. I'll never part with it. Almost 300,000 miles. Still going strong! Turned 300,150 in March 2023. Still a rugged and reliable truck.

My 1998 GMC Z-71 pickup was absolutely the best vehicle ever. Despite a couple of minor problems such as wiper motor replaced twice, intake manifold cooling hose attachment, right front running/low beam light working intermittently, and the steering wheel peeling after a few months, there were no problems other than normal maintenance. I sold the vehicle at 222,252 miles and it still used no oil. Not even any rattles at that mileage level. Great job!

Other than taking my truck back to the dealership seven times for the same water leak under the pass. side dash, I love this truck. Plenty of power, room and is reliable.
Best vehicle ever owned out of alot.

A 6 cyl, 5-speed. Must of been a special order as salesfolks there had never seen 5-speed in this when I went back last year looking around same dealer! Dealer reputation is horrible- will buy next one somewhere else. Wish I could find a 2002 or 2003 in 5- speed.Changed plugs at 110,000 along with fuel filter for first time(and it was clean).
a great truck

I bought this truck as a toy for my birthday. It was a used truck that can run on gas or lpg! I paid $3800! Great buy! This truck is amazing. It has 163,000 miles and can still do a 45 sec power brake. Easily do a burn out, tow anything and everything, and does it all with ease! I love this truck. It was one of the best purchases I have ever made.
Good truck

I bought the truck my senior year of high school and have liked it ever since. I added a high-flow air filter and a new exhaut. It now gets about 20 MPG. I hope to have a son one day that I can give this truck to.

driver door ajar, brake cylinder fails, alternator fails, etc., etc., and the "extended cab" with plumb seatbacks and about 8 inches of legroom is comfortable only for those under age 6.

Well taken care of, gently driven. Perfect truck for a student, work truck or second vehicle. Low miles for its age. Driven less than 5000 miles/year since 2013.
