My wife currently drives a 07 suzuki swift. However it is too small for her now with family etc. She likes x5's if I was to get one it would be the diesel model . The problem is that I'm not sure which year to go for including the sale of her car budget would be around 5-6k are they cheap to run? The other car i was thinking of was an lc4 landcruiser what would you get from the two?
