I wont be able to go to that Z meet this weekend but I plan on going to Englishtown, NJ next weekend for the autoX Z day. Heres a pic of me and my friend after autoX last weekend. I raced my RSX, still gotta break in the Z. He will be at e-town with his 300zx, that car is awesome!

 

I have the blue dot on my rims as well. But they need to fix that rim to make it right. What they are telling you is they don't want to pay for it. Repair should only be 50.00-100.00. But they need to make this right, man if they told that I would tell them to keep the car, or fix it or I walk from signing. But that is me. Right now you have leverage because the car is not sold. If they give you BS about driving it off the lot, most states have 72 hours -but you never signed any purchase order or lease/ finance agreement. There may be futher problems down the road. I am only giving advice from situations I was in.
