1. THE CAR
Picking the right car is winning half the battle. The popular notion is to drive something that is heavily armored. President Obama's presidential car, for example, is protected by 8-inch thick doors and is strong enough to withstand gunfire, bombs and grenades. However, not everyone is likely to have that kind of luxury. And the best car for the job is in fact the most common car you can find in your area of operation.
The reason is to blend in. For the most part, the massive limousines that you see used to transport VIPs are all for show. While that is all happening, the VIP is usually sneaked off in a much more discreet car. Pick a common car that you see in the area so that it won't attract attention and people won't even bother to take a close look at it. Of course, pick something that's fairly maneuverable too - use common sense.
