How much coincidence is too much coincidence?

A few days ago I had a very odd experience. I was driving home from work in my new car, and looked over at a car in the lane next to me. "Wow, that looks like my old car." It passed me. I noted the old Riverhouse and GWU stickers in the rear window. "Wow. That IS my old car!!" The car ended up driving directly in front of me for a while. Then it made the same turn as me... And then it turned into the same complex as me! Given that I've seen the car parked here since then, it appears that my old car just happens to have been sold to some guy who lives in this same place. I guess that means the dealership fixed the car, rather than selling it for parts...

Weird, though. My old car is haunting me!
