I got the v6 premium too. Same thing as yours minus the leather interior and pony package, and like I said mine was over $8000 less than yours.
Even at $1000 for the leather and another $2000 for the PP, you still overpaid by a long shot. The GT's that were out when I bought my car were about that much fully loaded. Actually they were a bit less. ($28-29,000)
