Paint or wheels or interior?

I have the car set up really nice (in my opinion of course), but I am getting ready for the next stage.

I have a nice smooth refinished body (except for final paint) so that's all that is really needed for the outside.

I have a really nice looking factory wheel set up now, but my goal is to end up with 13" wheels so I can put my 175/50-13 tires on.

My interior is almost complete as all I need now is the seats restitched and to lay the floor carpet down.

What do you think I should do? I'm leaning towards the inside since the outside has more of a finished look to it and the inside has bad carpet and a couple of rips in the seats.

Thanks. Later, QD.
