My 99 has 168K on the clock and is going strong (I just bought it in Feb.) Shortly after I bought it (March/April I think) I was towing my 28' travel trailer up a grade, had to slow down because of a moron tree hugger in front of me and someone closing in on the fast lane, put the skinny pedal down and passed the hippy, still going up hill, with a heavy arse 28' camp trailer on the bumper behind me. 100K makes yours just a baby... don't worry about it.
