It's a closely fought contest. The 1990 Mazda Eunos Cosmo 20B Type S brings quicker acceleration, lighter weight, better value to the table, and the 1988 Jaguar XJ-S TWR 6.0 answers with more power, higher top speed, greater rarity.

The rivalry between Japan and UK automotive industries has produced legendary matchups, and the 1990 Mazda Eunos Cosmo 20B Type S versus 1988 Jaguar XJ-S TWR 6.0 is among the most fascinating.
