Unless you're pretty handy and can take on 2 or 3 with baseball bats/knives/gun and be sure of coming out on top, I would keep the keys well away from you and your nearest and dearest. Its a car at the end of the day and isn't worth dying for.
Oh and welcome!
Fair point but no one is taking my car without a fight, no matter who or how big they are...................
But hey thats just me
It should be law that you can defend your property to the highest conclusion. This is whats wrong with this country today, discipline starts at home and in schools, its high time people were taught some.
