A good poor man version is to use an Apple Air Tag.
The pro is if it’s stolen the chance on the thief having a iPhone is high which gives you a good chance to locate it. There are a few draw backs though. You’ll have to activate the find mode on the AirTag every time you leave the car. The life on the battery is about a year but constantly activating it will reduce it significantly, maybe every 6 months? Also, if the thief has a iPhone he will be alerted that a AirTag is following him. This could be a good thing. He may just abandon the car if he realizes he’s being tracked. Before you hide the airtag make sure you remove the speaker. There are many videos on YouTube that shows you how to do this.
