2-Year Forecasted Depreciation
*Depreciation for the last 12 months of the private party resale value.
Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.

You’ll like the 2018 Mazda Miata because it’s cute, affordable and fun and you believe the journey is just as important as the destination. You buy this little sports car because you want it, not because you need it, and you’ll enjoy every minute you spend behind its leather-wrapped steering wheel.
For some the 2018 Miata is just too small and its 155 horsepower doesn’t pack enough of a punch. That’s why the world has Ford Mustangs and Chevy Camaros, two larger performance cars with back seats and optional V8s with gazillions of horsepower. The Subaru BRZ and Toyota 86 twins split the difference with tiny back seats and 205 horsepower.
