I've got pictures of the original ad on craigslist of the car, second/ third owner info as well. Second owner bought the car to part it out but realized the rarity being a factory 340 N96 car, and started collecting parts to restore. Sold it to the next guy who sold off most of the parts he had acquired to make money, then sold the car to James. James found just about all the missing parts (including the unobtanium 340 N96 base plate) so most ofthe hard detective work is done!
The car was repainted white way back in the day, so the ad shows White car. Guess In Violet wasn't a very popular color after the 70s fads faded.
Cheers
