Neither holds a decisive advantage, making this a true enthusiast's dilemma. Your choice ultimately depends on which driving philosophy resonates more with you.
When Germany engineering meets Japan craftsmanship, the result is one of the most compelling matchups in the classic car world. The 1970 Opel Manta GT/E and 1974 Mazda RX-4 Coupe embody their respective national automotive traditions while competing in the same arena. On paper, the two are remarkably close in power output, with the 1970 Opel Manta GT/E producing 105 hp and the 1974 Mazda RX-4 Coupe delivering 110 hp. Under the hood, the contrast is notable: the Opel Manta uses a Inline-4 CIH displacing 1,897 cc, while the Mazda RX-4 relies on a Rotary (Wankel) 13B with 1,308 cc. In the sprint to 60 mph, the 1974 Mazda RX-4 Coupe edges ahead at 9.8 seconds versus 10.5 seconds. The Opel Manta carries a weight advantage, tipping the scales 375 lbs lighter. Rarity plays a significant role here — with only 86,522 units built, the 1974 Mazda RX-4 Coupe is considerably scarcer than the Opel Manta's 498,553 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
