We were a Ford/Mercury family in the 60s and 70s, and are now mostly a Toyota one, so I don't know much about Chevys or this dealership. I'm saying that it closed in this millennium since there is a prominent URL posted on the building, but I'm pretty sure it's been 5 years or more since this was a going concern.
Actually following that URL leads to Capitol Chevrolet on Newland Road. This is that new dealership off of Clemson Road. I'm guessing they bought out Newsome in Columbia, though Newsome dealerships still seem to exist in other cities. (As an aside, this is the dealership with the humongous flag that I used for a 4th of July post. It was getting a bit ragged, and hasn't been up lately -- I hope they get a new one soon).
It looks like the old Newsome lot is starting to see some tagging and vandalism. I don't know who won the auction, but they need to get something going there pretty soon, or area will continue to decline.
UPDATE 30 Jan 09: Looks like the place is to be torn down soon:
UPDATE 13 April 2011: For some reason, the demolition never happened, and the place is still standing.
UPDATE 23 December 2011 -- And here is the still undemolished building:
