SOF...sorry, I don't agree. When I was working we all paid attention to the person filling out an app. or dropping one off...what were they wearing, did they have their own pen, did they bring anyone with them, etc. We could see their car usually and checked that out too. Some would come in all sweet and then go out to the car full of friends and kids and dogs and you could see the real person. If it was an older car, so what, it was the total package.
Go in clean appropriate clothing, have that black pen on you and put your resume in a nice folder if you can, not expensive, just clean and not wrinkled. If no folder, have a nice cover page and it's okay to staple it all together. Good luck!
