That sounds excessively expensive for a routine timing belt job.
At least you're DOING the routine maintenance. No vehicle will last long if you neglect scheduled maintenance.
I've stretched a 60,000 mile belt interval as long as 80K but no longer than that. As my car now has 240,000 miles on it,
it's been changed about four times. Next change due at 300K.
I refuse to gripe about routine and scheduled maintenance. Shit wears out and you have to expect that.
I only get grumpy about parts that break without good reason. Which, so far, has only happened ONCE on a 20 year old Toyota,
and that was possibly due to a mechanic putting in a rebuilt water pump the last time a timing belt job was done, about a year
ago. I can't prove it was rebuilt but I think it was. Never do that. New factory water pumps are cheap enough, no need to try
to save 20 bucks on a rebuilt one.
