After limiting myself to only advertising the car on (SSP/Mustang/Police) car forums, I finally caved in and placed a few ads on the local Craigslist listings, as seen here:

There's no need quoting the ad because this thread has more information than what I posted on CL. So far, I have gotten MANY more inquiries from a few days on CL than the couple of months on the forums. Sadly, most folks are only interested in it being a V8 notchback, and not-so-much the SSP history on the car. I have a few "live ones" presently, with one guy from New Jersey who sounds promising (in terms of providing a good home for the car).
