Reliability is out of 100, for the range of a generation's model years: its engine, its own known problems and their bills, parts and service costs, and age. Repair figures are the guides' estimates for an independent shop, not quotes. How the scores work

Most of the gap between years is age. A year is listed when the score charges it for something specific: a different engine, a problem that hit only some years, or a gearbox that came later. The same list for every car is on the best and worst years.
