It’s very fortunate for you that you’re here prior to signing.
This question demonstrates that you need to read the out of this website. Become skilled at estimating math and payments. Learn about MF and RV and how the play together. Brush up on the incentives and current residuals and MF for the cars you’re interested in.
Def be wary on the 39 month term. Here in SoCal where a tag is like $500 for that car, any savings on the monthly are quickly blown away by purchasing a tag for the last three months. You buy 12 months of registration and use three. It’s a big cost here.
$12K is pretty good for that car the MMR is $10.5K. How is this vehicle presently financed. I can understand rolling over equity if it means paying off that equity at lower interest rate. It doesn’t look like that terrible a deal for a RS, without the inequity your payment would be like $85/mo lower.
This car isn’t depreciating very fast at this point, and assuming a nominal refinance interest rate, an extra $500/month toward principal on top of your regular payment will have you about even by Thanksgiving.
If $500 doesn’t work, pick a smaller number and wait just a bit longer.
Remember in the first post where you asked the reading public for their thoughts? Just giving you what you requested. So, no, it is not OK with me. Well, OK, I don’t care, as it is your money that you are throwing away. But my thoughts are someone is being foolish with their money.
