Vehicles that you are ready to do something new with leave you with two main options. You can refinance them to save you on some of the interest rate. That will let you get a lot of value out of the savings. At the same time, you will have to accept the fact that you are going to remain in the same vehicle that you have now.
Trading in a vehicle is another option always available to you. It will let you get into something newer and better. However, it will also mean that you give up a decent amount of the value that is locked into the vehicle that you own now. You are taking the price that the dealer is willing to offer, and that is all that you get for it. It is not ideal if you care deeply about getting a fair deal on your vehicle.
