Just traded in my "01 Silverado for a "08 GMC canyon 2WD ext cab, with the 4 banger engine. A step down in size in power, but so far i'm averaging 19 MPG, compared to 15 in the Silverado. My work truck is a POS "05 dodge ram 3/4 ton service body truck. 44,000 miles, the tranny is whining, and the front springs are shot. Typical Chrysler crap.
97 Suburban 3/4 ton 6.5 turbodiesel. 198,000 miles, runs like showroom new. 99 Nissan minivan 105,000 miles. lots of nickle/dime problems lately. I'm not sure I would trust this on a long trip anymore. 81 Triumph TR7 90,000 miles runs- well, it runs. This is a summer toy. Wife has a 97 Dodge Intrepid ES 116,000 miles has been a great car!
