First tattoo (help me?)

They will take some tracing paper and make an outline of the area so they will know exactly how big the piece should be.

I'm not trying to change your mind on the mopar thing but you can never say you will never own any other brand. I said the same thing when I was younger and now I am drifting away from Darts and mopar body styles. You never know, just remember (as cheesy as it sounds) that any tattoo you get will be on you forever.
