^They are all quite different cars.
I drove the Charger for about 2 weeks last year, rental car, and my first impression was that it was a tad lazy and fat given it's engine size.
It is really quite a big car compared to our UK cars, we drove from New Orleans to Pensacola with 5 adults all with large bags and it was pretty comfortable for all involved (I was the driver so it didn't matter to me

). Over the course of the two weeks I grew to really like it, the boot is pretty generous however my lasting thought was that it does not need an engine that big.
I haven't driven the others however in my time I have driven a lot of estate cars and really enjoy having the boot (very good for dogs). One point to note that the estate cars I have driven tend to be a tad crampt in the back if you have a full set of passengers.
I really enjoy the driving style of Volvo and would definitely buy one in the future, I love the C30 previously mentioned.
Just to give a point of reference my car history is Vauxhall Nova (stolen), Ford Focus estate, Renault 5 (crushed due to the brakes being the worst the MOT mechanics have ever seen), Reanult Laguna, Renault Clio, Volvo V50, Hyundai i30 (pretty poor car overall), Suzuki Swift.
Of course it really depends on the distance you will be driving, how many passengers, dogs, equipment you need etc and nothing beats how you feel in the car always worth taking it on as long a test drive as they will allow you.
