GT or Grand Touring ?

[99 gt conv]

I own a 99 GT conv. 35th ann. When I try to book the car in NADA it has a catagory for Grand Touring and another for GT which is much lower priced, I can' find anything telling me the differance in the 2, can anyone point me in the right direction?

GT is technically Grand Touring.

Since they are missing the COBRA option for that year my guess is that the "GRAND TOURING" option is meant for the Mustang Cobra.

normal GT's are the Mustang V8 option
