- park your car in front of a shop or crowed people if something fishy is going on people will notice ..
2.put as maximum locks as possiable like china ,steering and others ..
3 get a chor switch but install it in a unique place like in trunk or other cool places like instaling it in one of your power window button ..
4.park ur car in such tight place where its hard to open the door and not easily to get a way in a hurry ..
5.get a good insurance no need for trackers or other stuff ..
6.if possiable see your car every min u get free if its still there nothing is happening to it ...
