Police officers were perplexed to find Stefon Diggs' Mercedes-Benz G-Wagon abandoned by Miami train tracks this month, with one cop even noting, "That's at least a $160,000 car!"
It's all captured on new police video obtained by TMZ Sports ... which shows Miami-Dade Police Dept. officers in the seconds after they were dispatched on April 18 to look at an abandoned vehicle near the Miami airport.
In the footage, you can see officers and other authorities discussing the ride ... and wondering out loud what it was doing there and how it got there.
