When we published Hagerty Insurance Co.s list of future collectible cars, one that brought that a lot of reader wrath was the Buick Regal GS, a new high-performance version of the mid-sized Regal.
"The Buick Regal - Ha!!!!! Not in this century," one reader commented.
In fact, the very idea of a collectible Buick seemed laughable to some readers.
Well, it's certainly not like it's never happened. While this Skylark was a fairly pricey car in its day -- over $40,000 in today's money -- it's really valuable today. This was a special edition created to celebrate the Buick brand's 50th birthday.
