No use if the thief is professional. This is only good for those newbies, if professional usually they will study or at least knew your car security system before go in for it. Previously i met an old "ex-con", he feedback early days already a lot of exotic sport cars or special limited cars with sophisticated security system also can get stolen. Usually they will do their dirty job in multilevel basement or underground carpark as where the GPS signal is limited, after gone out of the car park they will get another trailer ready usually with seal cargo container for the car to go in and you wont be able to detect where the car location.

Simple said, no way. If your car is marked, it will be gg anyway.
Every security system also got it's weakness.

The best way is to buy other rides which is not that easily marked.

No use bro, if they use tow truck can just pick up the front up and gg loo..

Yes. Not only that, previously a lot of rumors that near neirbour Thai border separatist also like to use stolen vehicle for car booming & terrorist activities. If you look at Hilux history with a lot of 3rd world country, it is a legend vehicle for those military usage.

FYI dee max sales is more better than hilux in Thailand.. dee max is a good reliable ride, i got friends owning it for years also dont want to change. Very fuel efficient and less issue.
