Help identifying car

Hi. I was driving behind another car (it was maybe sedan or sports car, not a SUV, van or truck) today that I had never seen before. I wish I had time to take a picture of the back of the car, but the only thing I saw was the word "limited" and a blue shield. No make or model or anything on the license plate frame that could help. I tried to get in front to see if I could see more, but it was a one lane road and the car eventually sped off. I'm just really curious what make and model it was, as it was quite a beautiful car. Does anyone have an idea? I tried Googling but no luck. Thanks!

The blue shield you mentioned - was it an oval shape ? Was the vehicle a 2 or 4 door model ? Was the vehicle a streamlined or box-like shape ? Describe the taillights as to shape and size ? Was the roof shaped like a fastback or more squared off ? Any other memories come to mind ?
