New from Iowa

Thanks for the welcome guys, I'd been on the B forum for a few years because my dream is to get a '67 GTX but they're out of my price range at the 'mo. So, I thought I'd have a go at my second choice of '66 cuda. eBay and Auto Tempest are my search engines of choice. I'd really like a good, legit Formula S but realize I'd have just as much fun with a regular 273. I'm all about originality. Is there a database on what VIN's were Formula S or was that not recorded.
