well, from seeing all the vibes here in my local area, their is only 1 1st gen vibe gt rolling around and 2 others in near by cities close to an hour away. not too common if i may say
Enter your VIN on CompNine and it will give you an idea of how many 2003 GTs were built, how rare yours is based on all the options it has, etc. (CAUTION: The information on CompNine is not always 100% accurate, but it at least gives you an idea).
