I had probably the very first '86 produced. Four weeks later, the powermaster went out, and the dealer replaced the entire unit. The same time, they replaced the turbo (car had 250 miles on it when delivered, so probably MANY people beat it up prior to delivery). Then, a few weeks after that, an insurance company called and asked to take pictures of the interior. Apparently, one of their insured had his car stolen and stripped, so the insurance needed to replicate the GN interior because the replacement parts weren't available. So, they went to embroidery shop to make the patterns, match the fabric, and so on. Probably used the standard Regal bucket seats and rear seat as a base.
The car lived on. The car was originally leased, and so I purchased it in 1989 for $7800 from the leasing company with 48,000 miles on it. Far as the leasing company was concerned, it was a six cylinder Buick Regal....!
