Suggestions Please...where to post a couple rollers

My father passed away a little while ago and I’m finally getting to the task of clearing out the garage.

I’m looking for suggestions on where to post a few cars.  Would there be any interest in these for the GRM Challenge? Any other suggestions on where to post them?

1987 RX7 Roller - bought it to make it into an SCCA ITS Car , interior is stripped. Car is straight, and rust free. Have at least one  additional differential and misc parts. Maybe even a disassembled engine.

2002 Mustang (SN95) Roller V6 5-speed- similar story...bought with intention of building an SCCA ITR car. Interior stripped. Have everything for it (seats, interior, etc). Low mileage engine and transmission (approx 65k Miles). 

I’m working to get pictures and an inventory of everything so I can post them appropriately. Any suggestions for where to post is appreciated.

Sorry for your loss. You came to the right place. Lots of good folk here.

Sorry for your loss.

Here, Craigslist, and Facebook are probably the right places to list them.  A few questions...

1. Where are the cars located? 
2. Do the cars have titles?  Are these titles in your name and if not do you posses the proper power of attorney so the cars can be titled in the potential buyers name?  Of course, some of this and the needed documentation varies by state (see question #1)

Don't know if it was there before but his profile says Buffalo, NY.

Thanks for the suggestions, I’ll gather more details and put together posts on them.

Yes, in the Buffalo, NY area.

Both have valid titles and can be transferred.

How much for rx7?
