I remember reading about people looking for the first T-Bird (I don't think it's on this earth any longer)
Actually, it's possible the first T-bird still does exist. I remember reading an article in Motor Trend Magazine in the early 70's about a guy who was driving past a used car part/junkyard and saw an old beat up 55 T-Bird sitting out front. He talked to the owner, and bought it for $500. As he was cleaning up the interior, he looked at the vin and saw the last four numbers...0004. He thought.. WOW..
this is an early T-Bird!! He wrote to Ford, and they told him that... 0000- 0003 were station wagons, therefore... he had the VERY FIRST production T-Bird. He immediately had the car restored.
As he was waiting for the T-Bird to be finished, he wondered if the 1,000,000th T- Bird had been built. Again, he wrote to Ford, and asked them to check the numbers, and if it wasn't built yet, he wanted to buy it. So Ford did check. They said the 1,000,000th T-Bird, a 1972, would be built in about a month--give or take. How's that for timing !! Ford made him a deal... after it was built, they wanted to use his 0001 and the 1,000,000th for a publicity tour to various Ford dealers... after that, he could buy the 72 T-Bird... which he did.
Now my long winded point... This was over 30 years ago, but given what these cars are, It's quite possible they're still around...
Sorry this doesn't answer the initial question.
