I think your car looks fucking nice.
You shouldn't even ask this question, it's your car and you do whatever you want to as long as you like what you did.

I don't ask anybody if they like my body cause it's covered in tattoo's and pieceings. It's mine and I do what I want. Your car is yours so do what you like.

I do think you might be better off taking the Alpine sticker off cause of theft idea.

Either that of put a sticker of the alarm system you have too. :P
I do like your car though.
