Can you recommend a small, 'premium' car with more space than a BMW MINI?

My mother currently has a BMW MINI (her second) and she really likes the quality, quirkiness and reliability of the car. However it is now used as an only car for her and my dad, and is not big enough...

Do you think the Nissan Juke's boot is big enough for a young family?

Thanks for your report on the Juke. My wife and I went to have a look at one on Friday night. We both love the look of it but my dilemma is the size of the boot. Do you feel this will be a suitable car...
