Comfort
                                        Passengers in the backseat will be able to stretch out a lot more in the Mercedes-Benz GLS 450 than in the FIAT 500X, due to its greater head- and legroom.
                                        As far as headroom and legroom go, there's not much difference between front seat comfort in the FIAT 500X and the Mercedes-Benz GLS 450.
                                     
Convenience
                                        With the Mercedes-Benz GLS 450, you will definitely be making fewer stops at the gas station than with the FIAT 500X, due to its tank size and fuel economy.
                                     
Cost
                                        There are a lot of factors to consider when calculating the overall cost of a vehicle.  The main consideration is Manufacturer's Suggested Retail Price (MSRP).   Clearly, the FIAT 500X is a better financial choice over the Mercedes-Benz GLS 450, when considering MSRP.
                                     
Dimensions
                                        Since the FIAT 500X is much slimmer than the Mercedes-Benz GLS 450, it'll be much easier to find a wide enough space in a crowded parking lot.
                                        If you go with the FIAT 500X, you'll have a much easier time finding a large enough space to park than you will with the Mercedes-Benz GLS 450.
                                     
Handling
                                        The FIAT 500X has a smaller turning radius than the Mercedes-Benz GLS 450, allowing you to more easily maneuver in and out of tight spots.
                                     
Performance
                                        In terms of towing capacity, the Mercedes-Benz GLS 450 is clearly the choice over the FIAT 500X for pulling heavy loads.
                                        When it comes to horsepower, the FIAT 500X has a lot less horsepower than the Mercedes-Benz GLS 450.
                                     
Powertrain
                                        The FIAT 500X has much lower torque than the Mercedes-Benz GLS 450, which generally means that it won't feel as fast or powerful.
                                     
Utility
                                        The FIAT 500X has less seating than the Mercedes-Benz GLS 450, making the Mercedes-Benz GLS 450 the better choice, if you need to chauffeur many passengers.
                                        The FIAT 500X has significantly less cargo capacity than the Mercedes-Benz GLS 450.
