The mini people-carrier vehicles are very good for families.
I can remember trying to take our two boys off on holiday in the UK in a Forde Escort in the early 90s and it was a nightmare getting everything in.
Then along came 'cars' like the Renault Scenic and the Citroen Picasso and they balanced space in a car without buying the bigger 7-seater jobs.
I must admit I like the look of the Qashqai. However as you say the Kia 7 year warranty is a big plus and again it looks ok.
One of the considerations of course is safety - I don't know how well built the various cars are if they are hit by something?
Bash-wise - at the moment we have a UK contingent of 5 so we will need two cars.
That does allow us to take 7 with your Audi and mine, or 8 even as I am sure Matt and I could both drive if we needed 2 x 4
Mogsam needs a push - he nearly came last year.
