looks like he is adding in tax. the tax difference should be less than $500 any unless their tax rate is crazy high. based on my quick math he isn't trading any vehicle in since a $23.5k sale price + my local tax rate works out to $481/mo at 4.9% with zero down. The OP is probably right that getting a new one is probably worthwhile since the total cost will only be ~$2300 more after all payments are made.
Yup, tax is already included in my math. Its roughly 30,000, give or take a few. They called me yesterday to offer me 3.9%, I took the time to explain my calculation and the manager just told me "look, it makes sense, I can't lower the price or the apr, it makes sense to get a new one" ..
I wish i had 23k lying around so I could pay cash. That'd be a great deal.
