WRX...Unless it's a little dog, that doesn't like moving about in the car and your kids have no legs.
Neither of my dogs will fit in the BRZ, that's what the Forester is for.
Same for family trips, we fit in the BRZ, but it wouldn't be comfortable or practicle for road trips, again, we have a Forester for that.
The BRZ is for my "Me" time....
