Investment Grade · Strong

The Mazda Eunos Cosmo 20B (1990-1995) represents strong investment fundamentals with consistent year-on-year appreciation, backed by bulletproof reliability (55/10) that owners routinely daily-drive and low running costs (82/10 maintenance). The RWD chassis has a loyal following among enthusiasts who recognise its performance credentials, and parts remain widely available (28/10). Clean examples with documented service history command the highest premiums; modified cars typically sell for less than stock. Now is considered a good entry point before values climb further.

Price estimates are based on market research and recent sales data. Values fluctuate based on condition, mileage, and market demand. Not financial advice.
