Actually (now that you've edited your OP) I looked into it and it's possible that your original stated color
might be correct. Right here...

..they do list a "Polar Silver Metallic." I don't know what year your Box is, but it looks like that color was available from 1999 - 2004. In my experience, that color is
really uncommon. I've seen lots of Arctic Silvers, pretty sure I've never seen a Polar Silver.
Take a look at the website and you can set the record straight. Or provide a pic or two. Either way you're right—they are fun cars!
