I don't think I can afford to do some of those to the car. They probably cost way too much. A few things I want to add and are also affordable. First is have a hidden switch to your fuel pump. place it somewhere that you can reach easily while sitting in the car so they wont have an idea where it is. Second is have your windshield and all the windows etched as it cost very very cheap to do and also helps when trying to recover your car if stolen.
