BMW x3 2d. Or x5 3d

[Owen42]

Hi I wonder if you could help me out.
Me & my wife are looking to buy a bmw x3d
As my wife has wanted one for a while now. We was going to look at a 2017 x line x3d with 60,000 on the clock with full bmw service history £14800.
But our niece has now just informed us she is selling ber x5 3d. They are the second owners off it & she bought from her boss who had it from new. & has every extra you can get on it again with full bmw history. & is willing to let us have it for less than what the x3 would be a lot less.
But our only concern is the running cost will be a lot more than the x3. Even tho we will be getting a lot more car for less money . Now we don’t know what to do! My wife does mainly town driven. Please help guys

Hi the x3 will be 2littre the x5 is a 3 littre.
Done an insurance quote the x5 is double what the x3 is, & tax is nearly double. I’m thinking the x5 is gonna to be all round more. Even if I get it cheaper. Plus like said if something goes wrong with the x5 will be awkward with family
