The photos chosen here do not reflect the similarity at all. However when you view the cars from the side profile the similarity becomes quite obvious. I have owned 2 BMW 635s and had people ask me if they were T-Birds, so this is not the first time I have seen or heard the two compared.
Opel GT and the Ferrari 246GT Dino. That's what got me into Opels. Had a string of them back in the late 70's. Still can't afford a Dino though. Maybe someday. Until then, I'll just have to suffer with my gated 360 Spider.
