Wolfgang: Thank you. Your response was very helpful. I will buy the book. I spent last night poring over and organizing probably a hundred or more receipts, something I never did after buying the car about 4 years ago. The original receipt says "Body Kit Complete Signal Red, black interior, charcoal carpet". It was $4000.00, with an approximate delivery time of 8 weeks. The other receipts support someone buying components to do a build, then subsequent upgrades or repairs over the years. Mine does have sunken battery box in the very front. I did confirm IM did not install wipers until the second mold. Paula Reisner was the quality control person at that time and she told me that herself in 2015 when I called. I know as of last year, Mr Reisner, who is in her 80's still comes to the factory Wednesdays and Thursdays. With photos and all documents I want to visit the factory in British Columbia, to see if I can get a letter of authenticity. Thanks again.
