31 – Cadillac CTS
Cadillac’s CTS is a well-designed, solid-engineered luxury sedan that is reliable road warrior and mainstay in Cadillac’s lineup. It does, however, also face the depreciation rate of other luxury vehicles and is higher than most, coming in at 36.9 percent. This means a 2015 CTS which brand new cost around $45k is now worth a little more than half that amount.
