Looks like it's an Avenger... I made a Google search and it gave me these pics:

It was also sold in the US as the Plymouth Cricket:

The car seems to be sitting there for a while... Looks like this Avenger will rot out if someone doesn't save it. This one is on its own way to a local junkyard already.
Btw, maybe that manual have a blueprint in? Have you checked?
