    Default Opinion about durability & fuel mileage of the Colorado

    Could anyone tell me how their Colorado has held up over time & what fuel mileage their getting with the V6?

    I have a 2004 Colorado with the inline 5 cylinder which Is what I think you mean, unless somebody did an engine swap to put a 6 cylinder in it? The only thing that has went bad was my gas cap, which the dealer did under warranty but this is a normal problem in any vehicle. Other than that absolutely nothing else has gone wrong, and I have over 75,000 miles on it to date.

    Before I lifted it and put bigger tires on it, I was getting around 26mpg average. Now I am lucky If I get 18mpg with the 33" tires, and 5" spindle lift.

    Welcome to the site ! Happy New Year! I have about 38000 miles on my 2010 V8 C/C and avg. 18 mpg. No real problems except for a tire pressure monitor went bad under warranty. I would be getting better mileage, but with 4:10 gears it isn't too bad.
