The 1975 Opel Kadett GT/E Coupe emerges ahead in most objective measures, offering quicker acceleration, greater rarity, stronger collectibility. The 1970 Opel GT 1900 counters with its unique character, but the numbers favor its rival. Still, both are remarkable machines, and the final choice often comes down to which driving experience speaks to you.

Overview

The 1970 Opel GT 1900 and 1975 Opel Kadett GT/E Coupe share a manufacturer in Opel, but that's where the similarities get interesting. These two models reveal the versatility and ambition of the Opel brand. On paper, the two are remarkably close in power output, with the 1970 Opel GT 1900 producing 102 hp and the 1975 Opel Kadett GT/E Coupe delivering 105 hp. Under the hood, the contrast is notable: the Opel GT uses a Inline-4 OHV 8V displacing 1,897 cc, while the Opel Kadett relies on a Inline-4 OHC with 1,897 cc. In the sprint to 60 mph, the 1975 Opel Kadett GT/E Coupe edges ahead at 10.0 seconds versus 10.5 seconds. Rarity plays a significant role here — with only 18,500 units built, the 1975 Opel Kadett GT/E Coupe is considerably scarcer than the Opel GT's 103,463 examples. Both trade at comparable values on the collector market, making the choice between them largely one of personal preference.
