I guess it depends on what you've got and how they've been stored for the past couple decades. Are the cars rust buckets from sitting outside or were they inside? What year are the cars? Really need some more information before I'm able to offer much advice. Can you post up any photos of the cars? I belong to a Z car club up here in Medford, Oregon and we were planning a cruise down to Redding in the near future... In & Out Burger makes it worth the trip.. At any rate, if we decide to make the drive down, maybe a few of us could swing by and give you our opinions on what you have... Just a thought.

pictures would really help

Agree with rainman, it truly depends on how these cars have been stored. On a slightly different note is if these cars are in decent shape do you have an interest in restoring them or offering them up to some one who would be interested.

I stumbled into what I reference the "Texan Twins". I was in search for a car but came across a gentleman who had two 71 Zeds and it was buy both cars plus nearly $10,000 of new invoice parts (proof is in the reciepts). Not trying to suggest you sell both as a bundled deal but if the cars have potential I am sure you will be able to find someone interested in them.

Would highly take rainman up on the club stopping by and give opinions/suggestions. It could be a barn find deal for some one so the Zeds legend lives on plus, $$ for your mom.

Good luck with them.
