Spotted this while browsing ebay. Listed as a 1985 Spoiler but looks more like a Persuader with a single pickup.

Yep. The P in the serial number ordinarily indicates Persuader, which shares a body pattern with Spoiler. Don't see these single pickup models too often.
 
It would be interesting to know if the black finish were original... looks like maybe a couple of the backplate screws are missing.
