We have three children and the Jazz still works fine for us. The boot is really big despite the fact that the car is small. We go camping with two adults, three children and all our camping stuff in this car, with no roof rack/trailer.
It's fairly economical to run too and Hondas tend to be very reliable. Ours is now over ten years old and running well.

i bought one of the first 1.2 models in 2004- mine was completely no frills (i regret not getting air con)

since then 100 thousand miles of happy motoring ensued. I had my first large bill this year at 105 k miles!

i don't recognise the comment about drive - i have driven this like a beast and it has never felt flighty - it feels rock solid and the ABS has stopped us from skidding a good few times.

the interior space is roomy, feels better than my sisters new model Yaris. DH is 6'2 and doesn't want for legroom. we get three child seats across the back.

The way the boot folds down flat is wonderful - we have moved house with this twice and it is used in lieu of a van all too often!

i had the new model for a week and it did feel less roomy inside - i think they have sacrificed some space to get the more attacking 'look'.

the 1.2 sometimes needs booting up a hill when laden, but that's what you'd expect.

Brilliant car as a working mum with one child -wouldn't suit if you had more than 2 though. All the seats fold down in different ways, so you can get them all flat. This means it's great for transporting stuff - you can get a lot in the boot anyway, but the flexibilty inside is good for holidays when you need to get a lot in. Also managed to fit in a flat packed, large wooden day bed + 2 mattresses from IKEA! Very reliable too, always passes its MOT!

I've had a Jazz for 4 years now & I love the space when you fold the back seats either down or UP. Loads of room for trips to IKEA or the tip.
