Well first of all I would like to introduce my self. My name is Kyle. I'm from a smaller town called Shorewood. We are right next to Joliet IL if you know where that is, most do because of Stateville (the prison). Right now I have an 04 Colorado that I am looking to trade for a Silverado, but I have a few questions. The truck I am looking at is an 01 half ton with a 3 inch susp. lift with wheels and tires, exhaust all the bolt on goodies. Anyway I'm just about to turn 18 next month and my dad is a little concerned with the truck because it has 97,XXX on the clock. I'm not too concerned about the mileage but he seems to be, and I respect his concern because he owns an auto salvage and has been dealing with cars for a long time. Well to get to the point, at what point did you guys start having problems with your trucks or have you not had anything major at all? We also own nothing but GM vehicles except for a Ford work truck. We have a 95 Yukon with 91,XXX on it and no major problems, my dad has a 01 Sierra 3500 dually with 26,XXX on it and no problems on either of them, and I haven't had any problems with my Colorado at all but that only has 30,XXX on it. I test drove the truck today and it's awesome, I really hope everything works out that I will be able to get it. Thanks for the help in advance.
