This lovely little creation is actually an old MOC of Flickr user Nolnet
It use a really nice combination of forms. It's retro because Nolnet only used parts available in 1987 and cabriolet? Well it's one of those rare open-topped blue and grey numbers that the Neo Classic Space scientist dabbled with - feel the solar wind in your visor man!
Edit: Thanks to the anonymous poster who pointed out my error when I said it was made with parts from 1978.
