There were quite a few kits made for the Ambassador Class Starships in Styrene Plastic (where she is more affordable and easier to work with), and most of these were primarily from ERTL/AMT, Platz and later AMT Round2. I'm sure there are resin kits made as well but for this highlight, we'll focuss on the styrene plastic kits.
Two scales were made available, the first being in 1/2500 scale which first came out with the Enterprise Set 2 and later under the Cadet Series on its own, and then the 1/1400 scale version. The 1/1400 scale even had the USS Yamaguchi version which was casted in transparent plastic for lighting.
Here's the 1/400 scale when she was launched.
And here's the 1/2500 scale version, when she first came out and her latest release. Much highlight have been given to this scale on the 1/2500 Enterprise set and the stand alone Cadet Series
Despite the grandeur of being able to own your very own Ambassador Class Starship, much care needs to be given to her accuracy, esp toward the shuttle bay which was the wrong design for the Enterprise C.
