2003 GMC Yukon New and ?'s

[fennsz]

I am contemplating purchasing a 2003 GMC yukon 4x4 loaded, with 94,000 miles. What are some concerns I should look for in this vehicle?
A few questions I have. it's the 5.3 with the E85 option. should I run E85? they mention a little less gas mileage with that. is it better to just get a normal 5.3L motor?
What kind of gas mileage should I expect with this vehicle?
thanks in advance.

i have the flex, and i think i have put E85 in like twice in almost 2 years, go for whichever motor has less miles

E85 does have about 15% less efficiency than regual gas and it does reduce horsepower aswell while you are burning it. I would only recommend you use it when gas prices are really high to make the fill up worth it, I wouldnt use it for anything else though.

i have the flex fuel 5.3 and i get 16 mpg on the highway on reg unleaded and about 13 with e85, so i figured it out that e85 would have to be 70 cents per gallon cheaper to break even
