I have had red, light blue, dark blue, silver/gray, and super bright blue. The ugliest, and my favorite, is the super bright blue. We bought it 5 years ago thinking in a couple of years it would be DS's car, so we let him pick the color. After driving it for two years I realized the visibility in it kind of sucked (it's a RAV-4) so I wanted him to drive something else.
But I have grown to love the color because I *always* know where my car is in a parking lot. I haven't had a single panicked "where the f is my car" moment since I bought it. From here on out I intend to buy the most obnoxiously bright car available.
