I didn't know you could get a window sticker too. Thanks for that tip. And WELCOME to the forumI called SVT and got a certificate of authenticity for my car. It cost $45 and is well worth it. The number is (800) 367-3788. If you do not have the original window sticker, SVT can also provide it to you for an extra $10. I also ordered one and have it carefully stored away!
