Finding your car in a crowded parking lot can be a nightmare, especially before the days of keys that automatically unlock your car for you (y'know, so you can use it for its real purpose, which is using the noise to figure out where on Earth your car is).
We've all had one of those times where we're positive that we're right near where we parked, but for the life of us it just doesn't seem to be there anymore. The worst part is when your brain starts to wonder about what could've happened, and then you start to worry about if your precious vehicle was stolen, and now you're stranded and going to have to call the police. Of course, we always find the car; it's just not usually anywhere NEAR where we thought it was.
However, in the case of one elderly German man from Frankfurt, not only did he not find his car, but he reported it stolen to the authorities, only for him to just stumble across where he left it 20 YEARS later!
