I didnt think we had one of these threads, so here goes!
I just ran out and checked my odometer. I bought my 2002 Envoy in 2004 with 64,090 miles on it. I now have 153,417. Just like age, it flew by!
What kind of truck do you have and how many miles are you at right now?
The wifes '02 TB was bought used in '04. Has a gentle 128K on the odo.
Other than batterys (on either its 3rd or 4th) it is still remarkably running on original parts....alternator, starter, suspension arms and joints, CV half shafts, exhaust.
Other replaced parts include front hub bearings on both sides, numerous pad/rotor replacements.
I love this vehicle, but it is 1 kid short to be useful now....we now have 6 in our family and this hulk only carries 5....
