True story:
Flashback to 1983, me and my friend are driving in the country, he has a 67 c-code vert and I have the 67 GT s-code fastback. We are talking smack about how cool it would be to see an old Shelby parked along side one of the many barns and farmhouses along the small highway. Not even five minutes later...no chit...we look over and see one on a trailer behind a trailer-home. After skidding to a stop we turn around and go over there. They guy says it was for sale. It was a early 68 GT350 with a K-code. No visible rust VINs looked authentic, backseat and trunk full of NOS boxes of parts and trim. Body was all primer but straight, original color was red
D), did not check for bondo. Started and ran smooth (solid lifters were music) but clutch was fried so it could not roll. Guy was asking $5K which might have well been a million to me back then. Sigh.
Closest I've ever come to a real deal like that, even though $5K was a little on the high side for a Shelby project back then, Minimum wage was $3.35/HR IIRC, and a new Mustang cost under $10K (for perspective). The S-code GT cost me $1,000 and it was 100% original and complete, paint was oxidized beyond hope and it needed a tune-up but it was heavilly optioned with the convenience group and tilt wheel etc. In the modern lexicon then a Shelby in project condition cost about 5X what a B-class S-code 67 fastback costs....sounds about right today. The complete 67-GT-FB would get around $20 which would mean the Shelby was worth $100K...errrrrr...wait a minute...not for a small block 68...big block 68 yes...big block 67 try $150. Oh well, still ballpark. The NOS boxes were probably worth more than the $5K he was asking, but go to a banker back then and ask for a loan to buy a 15 year old car...LOL.
You need to get out into rural America, away from the cities, into the red states. These cars ARE out there.
