It really is, being in WI but we drive through Chicagoland/Indiana and even into Michigan all the time for family and there really is always that one car that you just wonder how its still even moving.

I have a friend from the North Side and when we were young he'd buy these awful beaters for $50, not even register them, they would break down or get towed after a few months, and he would just buy another. They were no care, leave them anywhere and nobody would mess with them.

I would say that for sure, the GMT800 have achieved classic status and we'll see more guys buying them and restoring them. A lot of these guys will be the younger generation that remembers their Dads, Uncles and Grandpas owning them. They'll discover how simple and reliable they are, as new-to-them owners.

I considered selling my 99, sometime around 2015 or so, for a GMT900 most likely. Then a former coworker and friend suggested I keep it and said a lot owners hang on to them because the newer generations weren't living up the GMT800 standard. I didn't know anything about vehicles back then...Now in 2025, I would definitely agree 100%. And possibly, the bar has actually been lowered, which is pretty lame...

I would still have the 2004 K2500HD Silverado, if not for the fact that we were just not using it and it intimidated my girl. She loved the truck but was just afraid to dent/scratch it because it was so pristine. I thought about selling my 2005 Tahoe Z71 and just driving the truck as my daily driver. BUT, I really do love my Tahoe. I have put $ in to that Tahoe to keep it on the road and know the day will come for that 4L60E to crap out and I will fix it then.

If you visit the Tahoe/Yukon Forum you will see a very large contingent of GMT800 owners on that forum. For good reason. The 800's are the most dependable. The GMT900's and newer have problems, especially since the AFM came about. There is also the very large recall of the 6.2 engines for the most recent years. It is crazy and people are finding out that the more "goodies" that the newer years have, the more problems they have.

If you own a GMT800 truck/SUV, you are ahead of the game.

Some time after the GMT800 came out, I THINK GM got the idea that more and more people give up their new cars at the end of the lease,
GM started seeing new cars they were building more like the way Appl sees their new phones -
why make them last if they're just gonna 'upgrayedd' when the lease is up?

GMT800 was the last platform that seems more like it was interested in being kept instead of traded in at the end of the lease.
Respect to the GMT900s, but most of the best features on the GMT900s are either carried over or inspired by GMT800s.
My Tahoe may be the ugliest 30 year old Tahoe in 2032 ...
but I very much doubt there will be as many 30 year old GMT900s / GMTK2xx / GMTT1xx as there will be 30 year old GMT800s.

Wouldn't be surprised if this thing manages to be driving sideways on its 30th birthday for that matter.

I used to have a '72 C20 with a big block, put flows on it, a long time ago. Fun stuff, I suppose it was around a similar age to what the GMT800's are now. I have had newer trucks, and though I just like these ones, mostly have good power, and can do 70 on the freeway w/o having to be 3000+ rpm. Old days didn't matter as much as the speed limit was 55.
