Well I bought my Jimmy new in 1990 right as they came in with the 1991s. Mine had 30 miles on it when I drove off with it. Now the odometer reads 743,251. This is the truth. I drive over 60,000 miles a year for business and have since 1985. Yes, most of these are highway but that is still impressive. I also take it fishing a lot and to the beach on occasion. I had the transmission done at 427,000 because it was leaking but it was shifting fine. I have just replaced the basics such as alternator, battery, water pump, and mufflers. And just last month I had my heads redone. That is what I call reliability.
Well I bought this car with 19,000 miles on it and it will not stop running. Right now my odometer turned over to 277,000 and it runs like a new car with no oil burning. I have added many performance parts over the years and often take it to the mountains and beach. I hunt and fish with this as well as offroad alot. I have mine locked and geared raised on 38" TSL swampers.
