Hi, my wife and I are travelling in a few weeks and need to find a rental car that will fit our twins and their Chicco Key Fit 30 car seats. They are rear facing car seats. My concern is having enough room between the driver and passenger seats and the back seat. Will my car seats fit in a "mid-size" car - Hyundai Elantra or similar." We drive an Outback and then a Sienna, so we haven't had to fit car seats into a sedan yet. Thanks!
