According to Car and Driver, the cargo space of the BMW E91 is about 25%larger than the Infiniti EX35 and about the same as the Infiniti FX35.
The EX and FX weigh 200 and 600 lbs more respectively than the E91 and they are 4 and 13 inches longer than the BMW sport wagon.
I was considering the EX and FX but when I see their size disadvantage, the BMW seems like the clear value. Better gas mileage also for the BMW.
The Infinitis are nice vehicles and may be a tad faster than the BMW but the BMW rides lower and should handle better.
I wish a dealer near me had a new E91 on their lot to test drive. I am leaning towards the BMW the more that I research this.
Their exclusivity makes them attractive.
