I'm honestly in shock. I was in a random parking lot running an errand, looked over, and said "Oh my God it's my car!" The Penzey's bumper sticker is still on it and everything. It was either at the salon or the title loan shop (I was at neither of these places, for the record), but I saw no sign of the owner since I didn't go into either place. I wouldn't have bothered them about registration in person anyway. I did start to write a note to put in the vehicle, but decided against that too. So I snapped a shot of the car and it's new license plate, and went to the DMV. They were able to confirm that the car was finally registered out of my name 7 days ago. I AM SO RELIEVED.
Midori looked to be in pretty good shape. They had to have rebuilt or replaced the engine, and worked on a few other things, but it was nice to see her on the road again. What are the odds of running into the car in a county of 415,000 people? Had I not seen it, I would have never known what happened and might have carried the worry far longer than necessary.
Maybe the universe doesn't hate me after all.
