Car seat in a coupe

Shavanna

So my husband has a coupe. Currently using chicco keyfit and it's not an issue but was wondering if anyone has a coupe with a graco 4ever carseat. Or any carseat that doesn't come out of the car. Is it possible to have or does he have to get a different car. Trying to see if there is a way to get the baby in and out of the car seat
