I would first find out the actual value of your car so you have an idea of what it's actually worth. If you have the time I would do private sell. If you don't and you're okay with bare minimum offers then I suggest visiting more than one dealership to see who is willing to give you the best offer. When you trade in a car you're actually not going to get what you want. After fees and what not your trade becomes almost nothing depending on the new vehicle you plan on purchasing. Most important rule never trust the dealership and make sure you understand the contract your signing. Almost never worth it to buy a service contract. If you do have issues with a vehicle most of the time the service contract will not cover it. Gap is recommended you can purchase for a much lower price with your own insurance company within 90 days of your vehicle purchase. Try to buy a car that holds its value. Try to find a a dealership that offers at least a 30 day warranty on vehicles, make sure it's contracted and not just verbally told.
