They are two different type cars (obviously) but for kind of different uses. Its not "the 5 is a higher trim so better than the 3".Sure no problem, regardless of the country. If you were going to buy a 2nd hand BMW would you prefer the 3 series over the 5 series , vice versa and why?
If you want a luxury car that gets great gas mileage and are willing to pay a bit more, you are talking about a diesel 5 series (imho).True, luxury would be more important to me than a fast car. I love an eco car. I'm always willing to pay a bit more.
Do you know why the 5s is heavier though? Is it just because the body frame material is more or is the car larger?
You must be fairly young. Used and second hand are used interchangeably, at least in the south.Interesting that you refer to a used BMW as "second hand" I've never heard someone describe a used car like that here in the U.S. If someone has driven it before it's used!
