Most Honda engines have interference between piston & valves. So if the belt breaks, the piston comes up & smacks the valves. Then you get to pay WAY more than a couple hundred bucks.

Interference designs are one way Honda can get higher compression ratios & more power... Not all engines are like this, but Click&Clack should have known. Or maybe they were answering for that particular make of car? It's not only Hondas that are like this.
