What steps do I need to take in order to trade my car for another?

I have a 2011 Ford Fusion. It’s not that I don’t like the car, but I’ve always wanted something more sporty and fast.

I’ve taken an interest in a Pontiac GTO. I will have had my Fusion for a year this May. It’s up to date in all it’s payments.

I haven’t spoken to any dealerships or anything yet, because I don’t think I’ll want to do a potential trade like this until maybe spring time.
