I have a 2009 G6 GT Convertible that is very unique. It has leather interior with the GXP logo on it. I am told that a GXP convertible was not made, it also has the 3.9 v6 and several other options that did not come on the G6 Convertible. It is my understanding the order type is = 10 - P.E.P. / SPL EVENT which means a special event. How can I find out what event it was built for and how many were made???
