Almost at 220,000 miles.

- Plugs @ 2.5 years ago and they were toast.
- Rear end 3 years ago
- Timing chain tensioner went this summer, so new chains etc. Also fixd cam phasers while we were at it.
- Other than endless front warping brakes... so far so good.

 

My 06 SC 4WD has ~ 131K. Had to replace the laternator because the cases were cracked. Other than that absolutely no problems. Plugs changed at ~ 80K.
