^[COLOR=#red]61k miles on anything SRT is high mileage. [/COLOR]Because you know damn well that every mile was a hard driven mile, so in my mind I put that one mile as 2. So think of it as 122k miles (Its just my theory). Plus you dont know how the person took care of it.
NYCPosite: make sure first thing you do is get the spark plugs (every 50-60k you change the plugs), the tcase fluid, trans fluid, and diff fluid changed. And every 15k due to heavy duty use in NYC, you replace the fluids I mentioned except for the trans. Thats every 30k in my book for heavy use.
After you take care of all maintenance, enjoy!
