Looking to buy '71-73 240Z'

I'm new to this site. I've been browsing ebay for car and bid on a few in the last month. I had one which I bought used in 1977, but could'nt keep rust from forming. Got rid of it in '83 when floor rusted through. The car ran great and I must have put 60,000 mi on her. Must be having a mid-life thing going on because I want another one! Currently still have my 79 RX7 bought new, and on third engine.
