That Kings Ranch edition Buick is an interesting piece of history. I remember as a kid riding from Port Mansfield,Texas towards Brownsville in a 1980 Buick Skyhawk. Both sides of the road as far as you could see for miles were part of the ranch. I heard that through all of the marriages and divorces that the property has been busted up a bit. I know that there have been many Kings Ranch edition vehicles(Ford Truck)recently,but I never heard of that Buick before. Is this the only one in existence?
