Long-term lease/rental?

My parents totalled their car. We've been unable to settle on a new vehicle and I've despised the car shopping process.

Is there a short-term lease availability or a long-term rental option? We no longer have insurance because we didn't buy a new car fast enough, so any insurance will have to be either renegotiated or carried by the credit card.

Any suggestions? It is all a world about which I know nothing.
