This is the Bitter CD. We knew about the Bitter SC; this one was a surprise – today and 8 years ago. Yes, it’s basically an Opel. But one with a 327 Chevy underhood.
The front is pointy, with rectangular cutouts. I’m guessing pop up headlights. It’s not a Lamborghini Urraco (my first guess) or Espada (a name I remembered). Definitely not a Silhouette (aka jalpa). Renault/alpine maybe? Some bastard opel? BTW, the pink sky is not me being artsy – I COOKED my fricking camera.
