I am slightly upside down with my truck, I just checked on the online calculator and if I get a fuel efficient enough car I will get $4500 or if a small truck (which I need) $3500.

I owe almost $17,500. I can get right at $14,500 trade in. If I get a $13,000 car with $4500 cash for clunkers that means I would owe $11,500 for the new car correct?
