Could i trade-in my old car for two used cars?

basically i have have a 2005 toyota sienna


kbb trade-in value is anywhere from $16,975 to $15,425


in its current condition


what i wanna know is would a dealer even consider two smaller cars or even simply another car in exchange i want better mpg for daily work/home driving not 20mpg at best|||since it is 2005, then i would guess the dealership would give you about 14,000, you probably could get two 2004 or lower cars in ok condition.|||yes i would trade it in
