Can I lease a car with a 600 credit score?

It is significantly harder below 620, and most traditional lease programs through manufacturer finance arms will decline at 600. That said, it is not always impossible — some lenders run subprime programs, some vehicles have more flexible approval criteria, and some manufacturers offer special programs during incentive periods. The honest answer is that it depends on the lender, the vehicle, the month, and whether you have a co-signer option. At 600, the most productive step is usually to understand specifically what is dragging the score down before applying anywhere.
