Early 911-S spotted in West Seattle on 6/4. Anybody here want to fess up??

Rarely seen in the wild these days. Spotted westbound on Admiral Way, headed down to Alki, late afternoon. Male driver, from what I could see being directly behind Sorry, no pics. I often unplug when going to the gym and leave my phone at home. My somewhat educated guess is 1970, 1971. Slate Gray or slightly darker with some greenish hue?? Looked to be in really nice condition. Wider than stock wheels. Caught a glimpse of Fuchs while in a gentle corner . Surprisingly, had a modern license plate instead of Vintage or Collector plate. I didn't want to be a pest and chase the driver down to find out more, so peeled off at my exit street.
