Mine's about to hit 148k and it runs like brand new. Im with CoffeeAddict, it definitely needs new plugs soon. Not looking forward to that number 3 plug, but with all the threads about it, I should be able to learn a trick or two.

 

No complaints here, I bought mine (2000 LS 4x4) in 2010 with 168k on it, a Total wreck. Replaced everything from the windshield forward (Hood, fenders, radiator support, radiator, A/C condenser, All front Lights, Battery and Front bumper) after straightening the frame, and since then I've had to replace the alternator. All other issues have been due to abuse/neglect. Most recently the front differential locked up, and that was when I discovered there had been a leak and I'd lost all the fluid (who knows when). Still after sitting in the back yard for about a year, I was able to start it and drive it up onto the trailer to take it to the shop. Now it's back on the road, running as good as ever.

 

NOW at 190k on the jimmy... still running smooth like day one, the only problem is the 1 seecond puff of oil burn at startup from the valve seals. But, I do not lose sleep over it.

 

my '99 Jimmy is at 318,000 km, and I love the ol' beast. Just pulled the multi-function switch today, with much thanks to all the people in the past that have documented their own issues. U-joints all around, (hopefully), this weekend. I cant wait to get the old girl back on the road.

 

My 97 Blazers got 137k on it! Got it for cheap too. $2300 nothing wrong with it.

 

I just changed the oil at 190,000 km (118750 miles). I am hoping to get a lot more out of it since I had to put a transmission in it.

 

I have a 2000 Blazer 2x4 that I bought with 32000 miles on it.
At 176,000 I had to have the fuel pump unit replaced.
Not bad for the 150,000 miles I've put on it.
Still gets 20 MPG city, 24 highway (with ethanol contaminated fuel)

I hope to still be driving it at 250,000 miles.
That would be like driving it to the moon!

 

180k on my 2000 Jimmy 4dr 4x4. There are many, many new parts but it has original motor and tranny. I did not have to replace most of the parts because they broke, only because I really enjoy working on my truck!

 

as far as i'm aware it has almost 270,000 now got it with 225,xxx rebuilt the trans about 8000 miles ago in my backyard (my brother destroyed it by revving the engine to around 4k RPM and put it into reverse). i have also did the mpfi conversion around 3000 miles ago now my trans leaks fluid into the t-case but i love it

 

168,400 roughly. it runs like a champ, needs a few small odd and ends kinda things but its only getting better and better. it will have a 350 in it if this motor ever goes bad lol.
