Just curious what you now mean by "the yard" that is receiving all these vehicles?

Is this a salvage yard, your friend's lower-40 for storage, or the kiss of death crusher?
No judgments either way, but I'm keeping up with this like an automotive soap-opera in a way and wanted to get the story line correct.
I am glad everything is coming together in the end for you!

So after a week or 2 of REST! You'll have to host a part-shopping party in your newly organized garage full of stripped cars. Like a tupperware party for MB nuts like us
