The mikrus is quite well known and is in Julian Nowill's excellent book "eastern European Cars". Deffo a micro in my opinion! It also has possibly the daftest arrangement for a front opening door: side hinged is fine, roof hinged shelters you, bottom hinge lets rain and snow in and makes entering and exiting very awkward, and for those reasons I LIKE it! (Nuts!)
The other one may have been inspired by Goggos, but in reality the layout of the chassis and mechanical components, and the need for cheap tooling often has more bearing on the look of a car than copying another company's design. Look at Kaiser, Hillman, Standard and Fords of that era and they all have quite a similar shape.
