Totally understandable. But hey, the way I see it, you put all this time and money into your car, you definitely would want to protect it. If you could do something about it, why not?
As much of an inflated analogy this may be, I'd compare it to having a kid. You put so much time, love, energy, money, and all that jazz into it, you don't want to let your kid go out and get punched by some douchebag or bullied. *shrug* Maybe it's just me.
