Car seat for 2-door car

Hello! I’m looking for a recommendation for a car seat for my partners 2015 dodge challenger. Baby girl is outgrowing her infant seat; she is 6 mo, 29 inches, 16 lbs. I was looking at the Graco slim fit 3-in-one convertible, is that a reasonable choice?

There mostly won’t be other passengers in the car; my partner and myself are both 5’11”. I have an SUV, but he drives her to daycare 2x/week.

Thanks in advance
