Oh yeah, I'm very partial to the '87-'89s myself. Everything just seemed to come together those years for the Fox Mustangs in my eye with the powertrains and the interior and exterior looks. And every one of those years run strong right out of the box.
The owner of this '89 was a GSA auto tech and he serviced this and many other SSPs in the day and he kept track of this particular one until it became available to buy and then he jumped on it. I bet it led a pampered service life and now is an incredible survivor. He has been slowly restoring the original equipment to the car as it can be found.
