I got 3 estimates for replacing my timing belt when I hit 100K miles.

1.Dealership wanted $1400, this included replacing the water pump also, since it had to come off anyway.
2. Area garage that specialized in my make of car wanted $800, no new water pump.
3. Local garage that I had used with my previous vehicle wanted $400 including new water pump.

Went with #3, even though they were so much cheaper I was skeptical. 42K miles later not a hitch.
Pays to check around, and yes, Barbie, it makes your blood boil, but they will try it with a guy as well as a gal.
