Can anyone out there tell me what's so special about a GNX? Not only do they have the same problems a Grand Nationals, they have their own unique problems caused by the GNX specific parts. The handling is roughly the same as any other GN and the increase in performance could have been obtained by a simple chip upgrade and adjustable wastegate actuator.
I've had a GN for seven years before some liberated it from me and I've had a GNX for eleven years so I'm intimate with the differences. All I’m asking is what makes these cars the holy grail of the turbo regal world, other than limited production numbers?
