I believe this is the first time one of these has ever been offered for sale publicly, it is an unique opportunity. There are only 6 known to exist, and have been owned by the same people for a long time, and/or exchanged hands privately.
There are a total of 30 Buick lots currently registered for the sale, a very high number!
Some of them to note are...
1965 Buick Riviera Gran Sport $45,000-50,000
1958 Buick Wells Fargo Convertible $275,000-350,000
1954 Skylark Convertible $90,000-110,000
1987 Buick Grand National $30,000-35,000
It is going to be an exciting event this fall, I am looking forward to it!
