I have a similar weirdness in my back ground.
My first mustang was a white 84 gt that I bought on March 14th. After selling it and regreting it I went looking for another Mustang. I found a white 89 lx I liked and took it home on, yep you guessed it, March 14th. I sold the 89 after many years of fun wanting a SN95 mustang so I went looking for one. I found my current 95 at a Chevy dealership. I drove it on a Saturday and got a trade value for my car. I didn't sign anything but the sales person wrote up a high trade in appraisal to sweeten the deal. In Sunday's paper the advertised the car for $2000 less what they wanted Saturday. I went back on Monday and told them I'd take the car. Of course I didn't let them know I saw the ad in the paper until they started writing it up and then I whipped out the ad. Gotcha suckers!. They didn't not want to sell me the car for that price and give me the "sweet" trade in. So we went back and forth for almost a week. They finally gave in and I picked up my car on, yep you guessed it, March 14th. I start laughing out loud at the closing when I saw the date. The sales person got pissed until I explained it to her.
Btw I forgot to mention the 95 is white.
