Hello friends of Cougar.
I am from Pilsen in the Czech Republic. I am the owner of Cougar 1969.
I would like to ask you for a favor . I’m looking for information about my Heidrich Lincoln Mercury Inc. dealer in Peoria, Illinois. Or the first owner of "Carl Jelly Tremont Illinois.
I will be grateful for any information.
I think the owners name was Carl Gety, maybe Getty? Good luck with this hunt.
I think that the original owner’s name was Carl Getz
Whatever you need, Carl Getz? 
Google says he died in 2008, but his sister is still alive and a phone number is listed.
