You can always trade any car in that's worth something. If you still have a balance left on the loan, they can carry it over to your next loan if you don't want to pay it off first. Myself I'd pay it off and drive it till the end and then push it to the car lot, but that's just me. I bought a new car last year and the car lot told me it would be better not to trade in, just because they were not giving much since new cars had 0% interest and they were having trouble selling used cars. It really depends on what you want from your trade in, it may be better to sell it outright and take what you have left and buy a another one. Just an option!!!
