Bring A Trailer has been a good reference for valuation and, at some point, they added a graph that makes tracking prior auctions easier: Select a model to get access: https://bringatrailer.com/datsun/

Interesting to see it laid out like this, a black dot is a Z that sold a grey dot is a Z that didn't meet the reserve.

On the site, each dot is a link to the car details as well.

That's cool I didn't realize that

Neat! Here's my impressions after reviewing the dots:

• The general price seems to have gone up from roughly centered around 15K to roughly centered around 20K.
• There are a bunch of people out there that think their hunk-o-junk is worth around 10K (7 to 13), but the market clearly disagrees.
• There is one guy out there with deep pockets who hopefully got a fantastic car for his $40K!

I am thinking about 2 more years for mine to be listed there. Keep those prices up.

Mike Malamut bought it. Deep pockets for sure! http://malamutautomuseumfoundation.org/

Hagerty shows the lowly 73 240Z as sitting at $35,000 for a "good" one.  And their values are supposed to be base on actual sales.  Must be the from the bigger auctions.  Different worlds.
