FWIW, here is my experience almost 4 weeks ago when I bought 03 Z06...
I found this Vette on cars.com for 37K so I called that dealership just to see if they were willing to negotiate.
The manager I talked to was a very nice guy, he sent me many, many pics, both interior and exterior and we started to negotiate.
At first, he was willing to down to 35.5K and my counter-offer was 32K, now I knew there was no way he would drop 5k but it was a starting point for me. As expected he said there is just no way he could go that low and I told him that I am not willing to pay 35.5K either (btw, I was paying cash for it).
On Oct 6th, he called me and said the lowest he could go is 34K and my response was "Look, the C6s are out and winter is just around the corner and longer you keep that Vette, more money you'll lose" and I told him that my final offer is as following...33K and deliver that Vette at my house on Nov 8th at Noon (dealership is in Ohio).
On Oct 7th, he called me back and told me 33.5K, I stood firm and told him I am also considering other Vettes and that I was losing patience because I wanted to drive a Vette before snow starts and that if we don't make a deal by today, I am going to buy a Vette, locally.
He finally gave in and said we have a deal and his truck driver will deliever the Vette and I would sign all the necessary documents and give the driver a check for 33K. The Electron Blue Z06 showed up at my house around 11:00 AM on Oct 8th.
