Miles? I don't think so if it has like 110,000miles or less. Last year for the OBS I believe. So many less problems than the New Body Style. But that's just my opinion and I'm sticking to it. I might be concerned with ball joints going bad, in addition to any drivability problems. Namely fuel related. Make sure the intake gaskets have been changed already or you may be looking at a hefty bill. I would also change out the orange Dex-Cool also. Check out
www.Dexcoolcase.com for info about what some people are trying to do to GM. There is one particular member out there that is bent on getting me to stop telling people to change back to green antifreeze. I just provide information, it's your choice whether to use what I have told you about or not. As for my personal stance about your vehicle, depending on mileage and overall condition, I would not hesitate to have $2000 in reserve to buy parts that need replacement. Of course I do all my own work, and I have all the tools needed. Your bill may be higher. I am aware of all the little kinks and quirks that are associated with my truck and I am not mad if something comes up. For example, the intake gaskets, or fuel pressure regulator, the cap and rotor shot all to hell, and lets not forget any wierd tranny problems with the 4L60-E tranny. You should be lucky enough to have the 4L80-E, a much more stout tranny because the truck is a 3500. If you have any other concerns, feel free to shoot a private message my way. I love my 96 Z71 a whole helluva lot, if this 3500 is in decent shape, you may have a bargain on your hands. It just depends on what your breaking point is. Good Luck -Chris
