Can I finance a car with no credit ?

yes it all depends on the dealer you go to there's no credit checks and credit checks it all depends on your dealing and where you're going

Yes. There a a couple ways, 1) get a co-signer with good credit, or 2) you can still finance (usually) on your own if you have enough money for a good down payment and are not trying to buy an expensive car. But if you are looking at a 2004 Maxima, that's reasonable
