I bought what I thought was a dark blue Dodge Stratus in 1998. It was after dark and after hours when I first looked at it... and I actually wanted the black one next to it... The black one was sold, so I made a deal on the "dark blue" one. Never looked at the car again.. It was a new car and I was running all over the place for work at the time, so I did everything over the phone.
My soon to be ex-wife along with my kids took me over to pick it up..... They brought it out and I said "WTF?" and realized that I had bought a purple car. In the sun it was purple. In the shade, it was dark blue.
She started laughing at me... "You bought a purple car!" and the kids, who were 11 and 13 at the time started calling it the "Barney car" after Barney the Dinosaur.
