November 1998 the last Buick Riviera came off the assembly line for a total of 1,848.  Less than 50 known in the world!  Best car I have ever driven ahead of its time

Very nice car!

While '99 Rivs are certainly uncommon, there are more than 50 around.  Otherwise, I've seen 10% of them on local CL in the last couple years.  Cars 15 years old just don't have an attrition level of 95%.

Wikipedia mentions... "1999 was the last model year for the Riviera, a very short one, with production of 1,956 cars ceasing on November 25, 1998. The final 200 cars had special silver paint and trim, and were denoted "Silver Arrow"^[24] models, a designation which hearkened back to several Silver Arrow show cars that had been built off Riviera bodies by Bill Mitchell."

I can believe that only 50 of these 200 Silver Arrow cars whereabouts are known. 

That said, your Riv is a gorgeous car, and I still feel the '95-'99 Rivs are one of the best 5 cars GM has built in the last 20 years.

Lovely Car, Awesome effort at keeping it so nice and clean. Truly a collectible for the future. Here in Seattle Washington, the state gives special license plates to auto's that are 20 years old or older and identify them as collectibles. So 5 more years for your lovely ride. Keep up the awesome work.

Phenomenal car, I love it!
