Ever heard of a 1970 Olds W-31 Holiday? Me neither... I love learning about rare musclecars
http://www.barrett-jackson.com/carlist/cardetails.asp?In_AuctionID=221&In_LotNumber=635 Sold for 52 thou.... Hmmm. I have seen 50's Olds Holidays... but had never heard of one from the 70's. The specs in this link say Olds made 1029, and only 74 are known to exist.
