Have them change the water pump while they're in there as the timing belt has to come off for access. 105k is pushing it, I think it's good maintenance at 60-70k because of the interference engine. Beware of "come on" coupons in the mail as it's not unusual to get a $269 coupon and go out the door at $800+ with a pump, fluids and accessory belt. Use only new OE parts, not aftermarket or reman.

Good Luck!
