"Worty", who is selling this car used to own my current 289 CS.
He has owned a number of GT/CS's and other Mustangs over the years.
I contacted him last year after seeing him listed as a prior owner and he has been very gracious in helping me trace the history on my car. He is a very upfront guy in my opinion. Even after months of no contact he came across some old pics of my car from an old eBay ad at the time he bought it and forwarded them to me.
To add to that - I received an email today from the person that purchased my car from Worty who has even more history for me - I found out that he was responsible for putting him in contact with me as well.
If you're interested I would definitely contact him for more info.
