The term "variant" is commonly used to refer to a car which may be substantially different but would incorporated some major components of the original model. This might be same factory production of a differnet model. It could be a different manufacturer using the same engine or chassis parts. It could be someone using a complete running chassis with a different body type. With a little stretch of imagination it might just be the same engine used for an application that doesn't even have wheels.

I will use a very broad stroke here to include anything mechanically related to the MGA which is not a standard production MGA Roadster or Coupe. This is just a way to index all things somewhat odd or unusual. This will not be an all encompassing description of everything, but rather a cursory list to let you know what exists in the world of "special" MGA.
