The rear is where you really notice the difference between the 3 Series and larger rival such as the VW Passat. That said, there’s still enough space in the BMW for two adults thanks to the decent amount of leg room, generous foot space under the front seats, and adequate head room.
Shoulder space will be tight if you try to fit three adults in the rear, and the middle passenger will have to contend with the high central tunnel as well. But you can mount two child seats with ISOFIX points on either side of the rear bench.
Each rear door contains a small storage pocket, and there are adjustable rear-air vents mounted in the back of the front centre console. A folding rear-armrest containing two cupholders is optional on basic trims, while retractable rear sunblinds for the side windows are an option on all models.
