Attractive cars, although if you remove the long British license plate from the nose as in the picture, they look a bit gormless and slitty-mouthed. A couple came across the block lately and sold for mid-20s.
Problem with some of these cars is that while they were reasonably quick almost 30 years ago they couldn't beat a Honda Civic R today. That plus the parts situation keeps a cap on prices over here, anyway.
Find me a Cerbera, now, and I'd probably be arguing with the wife about what I'd have to sell to buy one....
