If you were in the circumstance of 'one car has to do absolutely everything!' the Honda Jazz/ Honda Fit 2002-2014 would be it. The origami interior - amazing versatile and usable storage - doors open at right angles; suit small family, will carry tall adults, 3 child anchor points, etc... It does all things well and nothing badly. Braking is brilliant.
Everyone who has been in it, likes it.
Rear seat room & comfort
I'm tall (6'1" or 183cm) - and I have an abnormally long back. The Honda Jazz (or Honda Fit) (2002-2014) is one of the few cars I can comfortably sit in the back seat. In most small cars - and some large cars - I touch the roof. Plus, the origamiversatility of the seating, conversion into storage is brilliant - and better than many far larger cars.
Powertrain performance
The 1.5 litre motor is 'wonderfully adequate'. I always use premium fuel for that little extra zip. The 1.3litre on lower RON is a little sluggish - but again, adequate. I've met many owners who are hugely content. They get better economy also. I get 6.4-7.2 litres to the 100km.
Fuel economy
I get 6.4L/100km usually; 7.2L/100km if I'm driving harder and using air-conditioning, have got 5.4L/100km in a 100kph long trip. 110kph gets ~6.3L/100km.
Tires
At 49,000km, I'm still on the original tyres; I expect to get another ~10,000km. I do corner hard sometimes; I'm also meticulous in checking pressures. I got Nitrogen put in the tyres at about 20,000km and I think this has been beneficial.
Controls and instruments
The ergonomics are very simple, very usable. Many more expensive or exotic cars are simply harder to use.
Driving position & visibility
The 'A' pillar is thick. I've 'lost' motorcycles or even small cars. Simple head-movements deal with this problem. Most modern cars have the same issue, because the cages are stronger.
Handling
Handling is predictably top-heavy. It is not a sports car. The electric steering is vague in a straight line compared to some; oddly, driven hard on twisty roads, it has a reasonably secure, predictable feel, the small vagueness of straight line is not noticeable.
Front seat room
Only 'just' adequate for me at 6'1"/183cm. Taller or longer-limbed drivers would have problems, probably. Headroom is excellent.
Warranty, maintenance cost
When I first purchased this in 2009, the fixed servicing costs were very competitive. They have risen about 60% since (most dealerships make more from servicing than sales) but are still comparable. In November, the 5-year guarantee expires; the dealer will never see this car again. I've a local mechanic I trust more.
Safety & braking
Braking is EXTREMELY good!
Brand reputation & image
Honda has a good reputation.
One of the best Value-for-money cars is the Honda Accord Euro manual - despite being a little 'old' now. If I needed a mid-range sedan, that's what I'd get. They are fast, and are aerodynamically stable at illegal speeds (180kph). The auto is pretty good. The 2.4 four-cylinder is faster than my (once-upon-a-time) Jaguar 4.2 litre - and uses less than half the fuel.
One would love the V6 Accord, but the power/torque advantage over the fuel penalty doesn't make sense at initial purchase.
This is an 'everything car' - not a specialist handling/no-space space/no-handling ecofreak/no-performance bias. For an 'only car, small family' it's a no-brainer choice.
