I was told recently by a Volvo dealer that my '96 854 is a GTA. I have been unable to find a description of what a "GTA" is. The car in question has leather, cd, cold weather, tracs, but no turbo, sunroof or passenger power seat. I was told when I bought it from the dealer that it was a "program car" (it was a year old w/7700 miles and had not been titled). Does GTA describe the option package in this case?
