On my wife's '97 Toyota Corolla has never been done. 130,000 kms. It's just a commuter car for her to get to and from work. I've had no symptems and don't want to drop $500+ if I don't have to. That buys a lot of gas during riding season. Will I get a warning prior to the worst case synario? Or where's a trustworthy tech to take it? Cheers Correction: timing belt.
