Different positioning, the 7 Series is the flagship model of BMW, focusing on safety and rear administrative protection. Due to the length of 5.2 meters, maneuverability is definitely not dominant compared with the other two models. Of course, if you compare 730LI with S or A8, it will definitely be more maneuverable. X5 pays attention to power configuration and road adaptation, and the driving pleasure in the northern snow is definitely better than that in 730 and 630.

But it's not without reason that you want to buy 630 ~

Your mother's side: I have a four-door car at home. I'll buy another 730. Besides, if I buy 730LI, the trouble of finding your home will continue. Will you go when relatives and friends get married and borrow a wedding car? If your family is in business, then the leader (such as industrial and commercial tax) asks you to borrow a car. Do you want to borrow it? There is another problem, fear of being kidnapped-this is actually very unlikely, but your mother is a lady, and it is estimated that people will be timid if they are scared ... In addition, the body is long and it is difficult to stop and park.

For your dad's side: 630 is 3.0 displacement, X5 is 3.6 or even 4.8 displacement, first of all, the fuel cost, and secondly, the current policy is very unclear, but the guiding ideology is to cut meat with large displacement, and now we are just discussing how much to cut. For example, the travel tax a while ago, and there will be various taxes in the future. No matter how the taxes are collected, the X5 with a displacement of 3.6 will definitely not be injured. So if you want to buy an SUV, you should wait and see. ...

As a result, your 630 succeeded.
