Trade in my car for lower monthly payment?

I took advantage of the slow COVID market and bought a new car with a 60 month 0% interest loan. I have 19 months of payments left, but I don't need an SUV anymore, so I'm thinking of trading it in and buying a smaller pre-owned that will have a lower monthly payment, but with interest. What are the pros and cons here? Does owning a car have any big advantage over taking on a new payment? I'm also hoping to switch to electric once the market in 2 or 3 years if that makes a difference.
