I give up, what is a 2-7-9 guy anyhow?

To give you an idea:

Timing belt alone/ parts and labor $250.00+
Idler gear, parts only $100.00
Tensioner pulley, parts only $100.00
Tensioner, parts only $150.00
125K service, at a dealer $75.00 or so
Labor for pulley/idler gear, 1 hour $90.00-$100.00

At this point you are at $775.00 before taxes and truthfully they will probably charge you more than the qouted $250.00 for the belt install. Why she is doing it at 125K seems a little odd, but it may very well be warranted depending upon the situation. Now if she was getting a 120K service (major service) and a timing belt, well then the $941.00 is not out of line at all.

Hope this helps, Mark
