Best suv for rear facing car seat

When I get pregnant, we will need to get another car. Mine is too small to properly put a rear facing car seat in. We want to get either an SUV or a van. We also want it t be good on gas mileage. Does anyone know of some SUVs that have good room for rear facing convertible car seats? Also, if you have any pictures of a car seat in your vehicle, can you put a picture so I can see how it fits? Thanks.
