I had a fellow to come in the car lot a week ago and when he came in he said you must like Shelby Mustangs seeing pictures on the wall. I said yes I have a few. He said his dad bought a racing Shelby new and used to race it. I said do you know what the serial number was? He said he didn't have any idea. He said I have a picture in my phone somewhere. I told him to look for it I wanted to see it. He found it and when he showed it to me I said I've seen that car before having the fluorescent painted valance. He said his dad painted it like that to distinguish his car from other Shelby's at Daytona on pit row. He said his dads name was Roger West and sure enough I found it in the registry it was 5R538. Here is the only picture he had.
