Your scores are not Fico scores or auto enhanced scores. So trying to make a determination based on those scores would not be very helpful. Having a few negatives will have some determination on the rate of the finance and will vary between lenders.
You mention the vehicle is in the 30K price range, and you are trying to get a minimum of 2K for your trade in and have saved about 3K in cash to put towards the down payment. You haven't mentioned what your income is which would help in knowing if you could afford that much car.
Simple scenario;
Car price of new vehicle -$30,000.00
Tax (based on 9.5%, your rate may be different) - $2,850.00
Total after taxes -$32,850.00
Total after trade in (if given what you mention) -$30,850.00
Total after cash downpayment - $27,850.00
Approximate Finance at different rates and years
5% - 7 years = $393.63 8% - 7 years = $434.08 10% - 7 years = $462.34
5% - 6 years = $448.52 8% - 6 years = $488.30 10% - 6 years = $515.94
5% - 5 years = $525.56 8% - 5 years = $564.70 10% - 5 years = $591.73
5% - 4 years = $621.37 8% - 4 years = $679.90 10% - 4 years = $706.35
5% - 3 years = $834.69 8% - 3 years = $872.72 10% - 3 years = $898.64
So depending on what rate you get and how much you make will depend on how much you can afford. You also have to remember that these figures do not include insurance, fuel, maintenance, etc etc.... which can increase these payments substantially.
