The Haynes big "A-Z of Kit Cars" has a pic of the Kingfisher Countess and yup, that is what you've got here!
It's not the worst Countach kit ever made, but If you put it next to mine, or a Mirage or Sienna then you'd notice that it'd need a lot of tweaking to get the body right.
If you can get it for a steal and you've got the space, patience, time, skill and tools then I've no doubt that you could make it look good.
Especially as there is rumor that long ago in the mists of time it was used as the starting point for the MasterCo! At least that's what Haynes think
But if you're not that good with fiberglass then i'd agree with the others, run... run while you still can, and don't look back!!
