1993 unmarked SSP (no agency listed)
 

This might have been a prior member’s SSP, because I recall seeing this unmarked Reef Blue SSP on this site or maybe the old .org site. It’s extremely clean with some equipment installed inside. No price listed.

VIN:

The paint looks good...in the pictures at least.

That appears to be FHP198 (the plate in the trunk is obscured). Here is the VIN Project page for the VIN listed in the ad -

I remember that the car suffered some front-end damage that was repaired.
