I'm glad that you think that way. Security is important to us, so don't cut-cost/save money on GPS, security tint, etc.

Haha, this one also depends on luck actually. If you meet those newbie robbers, then you got the chance to get back. If you meet those fierce robbers with full of hatred, you might see your own car burn, or worse, trade in your life too.

You can tint the front and rear windscreens with security films but bear in mind that security films have less heat (IRR) rejection rates. Both windscreens are the largest surface areas for sunlight and heat to enter the vehicle, so temperature will be higher compared to solar films.

Ultimately, for economy and practicality, solar tint for front and rear windscreen and security film for all side windows. In the end, its up to your pocket and preference.
