These are all from Go Away Garage:
Retractable fountain?

This looks like an Alfa-Romeo to me, but Go Away Garage is terrible about annotation. Tin Eye Reverse Image Search find one other example, but it's on Flickr Hive Mind, also without captioning.
Like a contemporary super car, it's got external ducting (behind the front fenders) and massive cooling vents — five gill slots, five mesh grille openings and at least a hundred punched louvers. I compare everything against the Volhart-Sagitta V2, and this has the same protruding pontoon front fenders and bubble top. Probably about the same interior space too.
Edit: It turns out Zappadong's Flickr page has information in tool tips. Here's the Wikipedia page on it:
