 I bought a used 2006 Tacoma with 109,000 miles on the 1GRfe engine.My Tacoma had one previous owner who maintained the truck well.After 3500 miles, I have had no problems other than having to recharge the A/C, a job I did myself in 20 minutes.Every gauge works, even the thermometer and compass.I am not a speeder and I am easy on my truck.I consistently get 20-21 miles per gallon on the highway.I don't know my city mileage .I hope the aluminum block V-6 can match the durability of an iron block power plant.I like my truck and expect it to carry on the Toyota reputation for reliability.
