Basically we are trying to downgrade in size but upgrade a little as far as MPG (So im told Highlander v6 not great MPG) But anyway, We currently have ab '05 Toyota Tundra SR5 Double Cab with 44k. We owe around 17k. The Toyota Highlander thats we are looking at is an '03 with 42k and they are asking 17,990. We would like to keep our payments the same but not sure how to approuch the car lot/ salesman. We havent looked at the car yet. Kelley Blue Book in excellent condition is 19,950 and the Tundra is 19,050. As you go down as far as condition they stay pretty close. What should we do???? Keep the truck or trade it. Any help is greatly appreciated.
