Always fun to see how you stack up, isn't it?
I'm in the same boat just on a different scale. I do okay on the autocross against them, but on the big track my lack of horsepower really shows up. Now my interior is nice but I run a G-body, not a Camaro so that dings me as well apparently.
I even finished out my trunk with paint and carpet but even that didn't help me any in the D&E portion.
Still way fun though and everyone involved in those events, the organizers and the participants...are top notch people.
