1985 Buick Riviera Convertible T Type VIN: 1G4EZ6791FE410655 1 of only 49 built with the 3.8L Turbo V-6 from the famed Grand National. This car cost almost double the price of the standard Riviera so you can see why there were only 49 made. This one was restored to almost near perfect condition. It came with all the options and we have a build sheet to show it. This car is powerful and drives like a dream. The top is excellent working order and the AC blows cold.
