This is a response to Jen M regarding purchasing a car using Honda Financing. A couple of points to consider
Once you sign a contract using Honda financing to buy a car (same with any dealer), its not a final transaction. The seller takes your offer and tries to get you the interest rate and terms. If the financing company does not agree to the said terms, the seller cannot sell the car - hence the calls days later about the car not being sold and to come back to dealer.
They have the right to also get the best rate and add up to 2% to the rate without disclosing what their best deal was.
They or the financing company can also change the deal after the fact. Case in point (we have 800+ fico scores at the time and unblemished credit) we bought a car for 3.9% financing years ago from one of the Japanese companies. It included upside down insurance for the life of the loan to make the total car price figures equate to the monthly payment (also, never agree on monthly payment - instead agree on total price). I was notified three weeks later that this GAP was reduced to 9 months - not the lifetime as put on the contract. Fortunately, I cancelled the coverage getting back $400 (it actually shortened the loan term by 2 1/2 months roughly). Others though aren't so lucky.
The above are reasons why never to take dealer financing - even if its 0% and always better to go through a local credit union or simply pay up front.
