I noticed over the past couple of years that when I drove my '95 300ZX (she was very clean, stock, garaged) that fellow 300's would flash their lights. I did like wise. Unfortunately that car met an untimely demise courtesy of a ill maintained p.o.s.
I've noticed that none of the 350Z's acknowledge me, no biggie, I tried with a few and quit. There was a thread on here that I thought explained that rather well, the 350 is a dime a dozen right now and not really being driven by only die hard Z owners.
What has surprised me is twice now(I've only had the car since August) I've had a 370Z come up and fall in behind me. I've tried a wave (as in nice car) but they don't reply. So not sure why they made the effort to catch up with me only to sit behind me.
But I like the idea of giving the other drivers a small parade of newer Z's
