About how long should I expect the timing chain to last? Have a 2005 GT-S, and the shop is telling me that I should replace it just because of mileage. I figure this may be a suggestion because I have boobs and thus will just take a mechanic's word for anything and hand over cash, but I'd really prefer not to if avoidable right this moment. That said, I'm also not wanting to blow out my engine.
