How much trouble to change the timing belt on the V6 XL7? It's got about 103,000 miles, but looks, runs and drives just like the day we bought it. It was my wifes car, but since she commutes 60 miles each way, the gas milage was killing her. We bought her a little Civic and now I got me a new toy! Got a lot to learn about these vehicles. Since we have had it, it has been extremely reliable. No problems at all except the front end doesn't seem to hold an alignment very well.
