The most I've ever gotten pull over in is the butt ugly Taurus I used to own, maxed out speedo on a 65 zone
second most is in my ex's Honda Accord seden, never in the MX-6... I guess the Taurus and Accord look hella faster
Seriously, that's not how cops pick what car to pull over. It's more like their radar detect a sine wave that indicate you going way over the speed limit, or you just driving like a jackass, which 99% of the speeder do.
