I only discovered these kits a few years ago. Not being into circle track at all I just thought these were just another stock car like the hundreds of other stock car kits out there. But the engineering in these, especially the exhaust that goes through the interior is unique enough for me that I am intrigued. Out of the whole batch my favorite is the Camaro, but would take any/all of them if Round2 wanted to invest the dollars. I did buy the GTO and will pick up the Monte when the timing is right. From my perspective it's kind of a no-brainer to do the rest since all they need to do is tool the body bits, of course depending on how well the GTO and Monte are selling.
