Since buying my Sierra new in Alabama, I have lived and worked in Louisiana, New Jersey, and now West Texas. I've been in mud, sand and water up to the front grill and in 4WD Low the truck is unstoppable! The tow/haul transmission mode is great for pulling the boat. I've had no mechanical problems whatsoever. The few drawbacks...should have bought the bench seat vs. the buckets- more passenger room and could have sat closer to my girlfriend! Four doors would be better than three. Cruise control accel mode is touchy..tends to downshift the transmission for accelerations at highway speeds. All in all great performance, styling, and durability.

I have a 99' GMC SLT with the Z71 option. I am extremely satisfied with this truck. I previously owned an F150, the GM beats it in every category hands down. GM also has a far superior service department, this point I cannot stress enough. I highy reccomend purchasing one.

bought 2wd SLE, 5.3L V8 new in may 1999. still using the orignal brake pads and spark plugs. starter dead at 110K. Started leaking oil at rear seal about 60K. Let leak for the next 60K miles before I had a mechanic replace the seal for $572.00. enough said - it's ok to top off with fresh oil. I've actually drove it around for quite a few days with the check oil message and then had to add 1 full qt. This truck takes my abuse. Trucks gets 15mpg, no matter what. Interior headliner is starting to peel, pass side electronic window cable broke-who designed this??? AC blows as cols as ice. Friends who have newer Chevy's have more problems that I. CD player skips now. Very happy with it so far!

I just got this a few day s ago and here are my first reactions: I have the 5.3 V-8 and it preforms well. Although it doesn't have the power of my Z-28, it can move fast enough. The ride is better then the fords I looked at. The Auto 4WD is good, but you may want to turn it off for parking. It is very comfortable and fun to drive, it is a truck that you can do stuff with like moving and off road driving but it can be driven every day. I will try and write an update after i have drivin it for a while.

My Z71 has been nothing short of the best vehicle I have ever owned. I have driven it very much on long trips and it is an awesome truck. It has never let me down in any task I have required it to perform. I'm a firm believer in the fact I will be a GMC man forever.
