A thread on Reddit has emerged which shows a picture of a 1968 Shelby GT500KR that appears to have been left out in the elements to rust away. The title claims that it is 1 of 4 that was produced in blue with white stripes. With some 933 produced in 1968 it seems unlikely there were only 4 produced in this color but this author was not able to find any information to confirm or disconfirm this claim.
A restored version sold for $132k (with buyer’s premium) earlier this year at the Barrett-Jackson auction. See it here: restored 1968 Shelby GT500KR.
In 2001 a 9000 mile unrestored survivor that was displayed at SEMA sold for $250k (with buyer’s premium). Hemmings has a few for sale with the cheapest (at this moment) at $105k. Collector Car Market shows them with a range of $35k-$179k and Hagerty’s Valuation Guide, shown below, pegs a #3 condition car at $109k.
A proper restoration would not be cheap but with a value of $100k+ this specimen is definitely worth reviving.
