That's me these days, except they buy me a new truck every three years. I have the oil changed regularly (every 6K miles, love that synthetic... and no dinosaurs died to make it, either.I don't know what to say. I trade my trucks every two years due to mileage and tax purposes and I haven't opened up the hood on the last three. I'll also tell you, I don't know what's under there anyway....
The only reason that I pop the hood is because somebody needs a boost.
There is a difference though between a vehicle used daily for work, and a commuter and/or retiree vehicle.
As pointed out earlier, I drive 3 times as much as most people. That results in 3 times more repairs, but also way too much down time if running older trucks.
