Turbo Boxer

I've always loved the 240Zs but the thought of restoring one have only recently been financially feasible. I must admit that I don't know much about them and as you can tell...do not own one at this time. I am currently looking for a 70', 71' 240Z and want to spend about $5k in acquiring it. After that, I will restore it slowly based on my budget and available funds. Any advice would be much appreciated. Also, does anyone know of any 240Z car club in Northern California? I live in the SF Bay Area, and would really like to meet and talk with someone who has done the restoration. Thanks.
