Cost
The destination charge is a standard charge for transporting the vehicle from its point of origin to the dealer. It costs roughly the same to get the 328 to the dealership as the Infiniti G37x.
Producing a precise gas mileage evaluation is so tough that some think not even the federal government can do it, but it looks as though both the BMW and the BMW perform almost similarly as far as gas mileage.
When it comes to MSRP, the G37x costs about as much as the BMW (though the BMW is a tad cheaper).
Utility
Neither the BMW 328 nor the Infiniti G37x has a marked advantage regarding seating capacity.
Convenience
You will most certainly have to visit your friendly gas station more often with the BMW 328 than with the Infiniti G37x.
Comfort
Taller drivers will considerably enjoy the extra head room in the Infiniti G37x's front cabin compared to the BMW 328.
The Infiniti provides more head- and leg-room to your passengers than the BMW does.
Dimensions
Your wallet will hurt more every time you fill up the Infiniti than the BMW 328 because of its bigger tank.
The BMW and the G37x compete for the same parking spaces.
Performance
In terms of horsepower, the Infiniti packs quite a punch and will knock the BMW 328 down a few rungs. However, note that high horsepower engines often command higher insurance premiums.
With that kind of horsepower, the Infiniti G37x is a genuine sports car.
Drivetrain
The Infiniti G37x has a bigger engine than the BMW 328. Note that smaller engines are often cheaper to fix, but smaller engines can be stressed more.
The G37x packs quite a wallop compared to the BMW 328 as far as torque, which is roughly equivalent to acceleration.
The BMW 328 could learn a lesson or two from the Infiniti as far as pickup.
Warranty
The basic after-sale protection that comes with the BMW 328 isn't quite as generous as the Infiniti G37x's.
