Hi
i found on the german site
www.carcarrier.de the "eternal ace". in my view it's the only real sistership, which is exactly designed in the same way. it was build already in 1988, cougar ace was build in 1993.
there are many carcarriers of mol, which are very similar, like pearl ace, frontier ace or cattleya ace, but at least there are differences in some details.
Hope that i could help you a bit.
Best regards
Torben
