Do a Google search. There are reviews in Car and Driver, Hot Rod, Road and Track, Autoweek and many other magazines that offer good online articles. Also Ford's website has the info too. From what I can tell, there was only one GT350 made with no options.
Details please- year, options, condition, color, reason seller sold for that price on ebay (base model?)
Also, please post in new thread - suggested title "Buetail's GT350". This thread needs to die off.
Congratulations, it's a great car!
