Is it the color Sepia Brown? Is it overpriced at $80-$90K? Is everyone waiting for Monterrey? Market finally slowing?

Not sure what the issue is, but would appreciate any constructive comments on why I had some very strong initial interest in my 72 coupe (see For Sale section) and now crickets. Generally I have a very good finger on the market but to be honest I am kind of lost here; I have seen much lesser cars go for strong $70's and $80's or rust buckets going for $30's and $40's...all non S cars.

I did not purposefully restore this car to flip, but to actually enjoy, but I started 3 years ago when prices were reasonable. The car has absolutely everything done right, so not too much I can see that I missed. Lastly, I do not want to get into the price escalation debate, but I am one of the owners who has lost some interest due to the price increases and I actually do not feel okay driving this car like I intended....

Any help would be appreciated!
