Greetings!

You are very lucky to get it back. There is still the car damage, and (from the sound of "smashed") quite a bit of repair on the empeg itself, but you might be able to salvage something...

One interesting point, though - I hope you handled it carefully to try and get fingerprints / get the police involved. Since it was found so close to home, that means (assuming they stole it from your car parked at home), they did not take much time to study or work with the unit. If they were in a car, it would have only been seconds; on foot, maybe a minute or so. In any case, the thieves are likely still in your neighborhood.
