My mainteance and repair cost so far with 16 months of ownership. Bought with 130k miles, now have156k. I pretty much daily drive her. Not including oil changes or the 1 set of tires that I put on which will probably go 60k miles before they need replacement. This was a well cared for truck with a pretty good service history.

1. Battery upgrade to AGM - $180
2. Front Centric premium rotors and Akebono performance pads - $160
3. Diffs and Transfer Case fluid change - $120
4. Trans fluid exchange with filter - $340
5. Wheel well splash guard rubbers - $60
6. OEM Denso reman Alternator and belt - $240

This was the minimum to keep her running well and to be assured that it has good fluids. Of course I've spent about $1400 on some small cosmetic fixes, upgraded HID headlights, wheels, hitch and such to make it useful for my purposes.

At 160k I'm going to do the timing belt, water pump, etc which will be about $400 in parts.
