If you haven’t caught this USA Today article (posted first by Motoring File), then it’s definitely worth checking out.
Special models can skew depreciation. Sports cars, some luxury models and others with strong appeal to enamored buyers hold their values well. Thus, the Mini Cooper S and the Mazda RX-8 sports car are expected to depreciate slowly.
Sure, another article about how well the MINI holds it’s value (Roxy is still pushing $16K high KBB with 65K miles on the clock), but it’s more about car values in general, less about the MINI. Very worth while read.
