If you can get your hands on a Toy 4 Runner there will be no disappointment. We have a 2006 Toyota Four Runner Limited V8 with 140K reg maint and tires. I drive city and highway constantly and average 16MPG. And the new ones have 18/22 City/Highway sadly they are a little more than 5K for new. Had to correct the MPG put 20 gallons in and get 320 miles with bout 1/2 gallon left.
