55,650 on the clock. Only issue so far was a couple of weeks ago when I had to get the coil on #5 cylinder replaced.
*edit - Also had the diff fluid replaced due to the grinding noise about 4 months ago. All is quiet in my rear now. Uhh...nevermind.
CPO until 4/15 and the maintenance plan to 100K...so far I am a happy camper.
