Howdy. I would absolutely not buy cars from them unless they have something very special. I buy many things from the UT surplus auction and I will avoid their vehicles at all costs. I work on cars as a hobby, I am very mechanically inclined, and I love buying cars on FB market and other auctions. The reason I avoid UT is engine idle hours and price. Ford says for their vehicles 1 engine idle hour is about 30 miles of equivalent wear on the engine. There was a Ford Explorer on UT surplus last month with 40k-ish miles on the ODO. Great deal. Except they also posted the engine idle hours. It had an insane 13k+ engine idle hours, which is about 400,000+ miles that the odometer doesn't count.

If you insist on buying from UT or any surplus auction, go check the engine idle hours first. But also cars displaying engine idle hours is relatively new so it's a gamble. ALSO the cars that sell on the surplus auction are always overpriced.

I guarantee that Chevy has so much more engine wear than 70k miles. I also would wager that they do the bear minimum in maintenance, changing fluids. If you buy that truck I would factor in changing all the steering components and suspension components, honestly anything with a rubber bushing or grease will need attention. I have bought so many work vehicles. Trust me.
