Sorry for the delay in replying. I'm well aware of a few unfinished cars that were sold off at the auction. (a friend of ours has one sitting in his garage that he purchased at the auction over 30 yrs ago) This particular car that I have was bought from Weitzes Motors Limited in Willowdale, ON in November 1982 as a body and frame only. The family I bought this car off explained that the gentleman had been collecting parts for it over the years until his passing 6 yrs ago. This car came to my attention last year and I've been slowly putting the gathered parts onto the car and hopefully will be able to get it on the road this summer. Speaking with a well versed Cobra enthusiast friend of mine from Ottawa, he mentioned to me that there were 3 prototypes built and that one of them was located in the Prince Edward County and this is where I purchased the car from. In our conversation, I mentioned that the doors were heavily modified and mocked up for pre-enginieering test fit along with a few other parts. With this information I think this may be one of the 3 early prototype cars. If anyone has other information regarding these early cars, please let me know.
