I can only say that this vehicle will go up in value with age. Unlike many others. A true collectors item. Most people that have them tend to hold on to them. It took me 5 years to find the perfect stock gold edition Riviera I am now driving.
GM needs to carry better inventroy of parts for these cars. They only carry 10 years worth of inventory as I found out. Sad to say but this makes these cars even the more valuable.
