There's a single owner '04 Yukon Denali XL for sale near me. It's got a slight lift, not sure of the brand yet. Looks to be in very good condition and has been in a single family its whole life. The only hang up is it has 172k miles. Seller is asking $4900. How reliable are these trucks? I'm not concerned about MPGs and need a family hauler for an outdoor oriented family. Would you steer clear at such high mileage?
