 Bought Dora (The Explorer) in 2004 with 40K miles on her. 4.0l V6. To date I have replaced the thermostat, both radiator hoses (innie and outie), brakes, serpentine belt and tires. She has never let me down and has 150k on her. The most reliable vehicle I have ever owned, hands down. This is one of that last real SUVs - built on a truck chassis (Ranger platform). We lived in mountains of northern New Mexico and spent a lot of time boulder crawling on two-track roads along mountain ridges. Great 4X4 capability as well as highway capability. the ride is a bit bouncy, but I tamed it a bit when I put a set of bilstien shocks in place of the factory ones. The explorer is paid off and still alive
