What's the best way to shop around to refinance my car?

How I will try to get the best deal out there , because now my payments are a bit too expensive ( $ 405/month ) to be exact . MedlinePlus I can not afford that much right now. I'm thinking of selling this car . But I think you might as well just sell refinanance before (maybe two months in the future) MedlinePlus MedlinePlus MedlinePlus Also I have some guarantee of wheels and some other additional warranty on my car ( $ 2,000 penalty ) . I was naive when I signed it. MedlinePlus MedlinePlus Will also be included in the loan or independent ?
