Wait, do they really want stock, non-classic cars at this show? I mean I can understand a heavily modified car (like a race car), but one made in the last 10 years with some aftermarket rims and not much else is what they want for a car show for the general public? Are they trying to use this event to raise money? If so I would think they want unusual cars to draw in people? The general public doesn't care about modified Subarus unless they are really over the top I would think. Otherwise it's kind of like just walking through a dealership lot.
Or is this more of a club type gathering?
I would just be careful that you don't over run your church with a club of Subarus rather than true show worthy cars. If you still want us there, that's awesome as well.
