True, but a chain only needs to be replaced when you rebuild the engine.
A chain that lives in a nice clean oil bath will last much longer than a
timing belt.

Chains break much less frequently than timing belts. They usually give
you some sort of warning in advance, by the noise they make.

Actually it does matter because belts have a shorter life span than a chain.

Not just theory.
