I could never find any documentation around the turbo coupes for 78.- 80. I've heard 69 total of which I've saved five and still own one. I know of one 79 turbo 4 door. The aeroback four door was only made in 78 and 79. 80 went to sedan look for the four door, while 2 door remained aeroback.No worries, ill try to explain to the best of my abilities, so don't expect much 😆 In 1980, Buick was literally all over the map with what they used and what they turbo charged. For the Century in 1980, even the century 4 door could get the LC8 ( Turbo 3.8 V6 Option). As far as the Century Coupe, they used a couple of different body codes. 4AG87 and 4AH87. From MANY years of research and actually being able to speak to individuals who worked the assembly line who had documentation, The 4AH87 body code only seen 10 LC8 Turbo examples produced AND was first to be assembled during the Turbo Century Coupe run, the 4AG87 seen 147 examples produced. I love doing research and verification on these forgotten cars, because its sure to be lost history and needs to be saved and appreciated. These cars were the predecessor to the Grand Nationals and truly have a lot of history. Thanks for the compliment and thanks for your question! 🙂
Is your car buckets, console and any other options?
