Answer: -What type of car are you looking to purchase? Some lenders, like Ford Motor Credit and GMAC, will approve your loan based on your tier level, which includes credit score, job time, residency, debt-to-income, and loan-to-value. Each situation is unique, so it's hard to give you the best advice without more information.How much do you owe on your current vehicle v/s the payoff?What are you looking to purchase? New or Used? -I was in the same exact situation not to long ago. I went to a honda dealership and bought an 04 civic with low mileage. My advice is to just keep looking, look at the bigger dealerships they usually can offer you more for your car even though it might be worth less. Also make sure you go in with the I know exactly what i'm looking for attitude and they will usually work with you. Just keep looking, it took me 2 years to find one. Good luck oh and i have horrible credit too. and the bigger dealerships can usually help you out there too. -It all depends on what is driving your score down. If your FMCC loan is constantly late, it is going to majorly hurt your chances of getting another car especially if you are upside down. There are companies like Americredit, Capital One and Drive Financial that can help you, but if you are in an upside down position on your trade you need to come to the table with some money down. Also, you need to look at cars with rebates to help offset your negative equity. These companies I mentioned before are ones that dealers use. Some dealers don't want to deal with people who have some credit issues because they don't have anyone that knows how to work with those companies. Check your local paper for dealers that advertise for bad credit. They usually have departments of people who specialize in just your sort of delima.
