Used to have an 1.2Jazz for few years and covered LOTS of miles with no problems whatsoever with it.
Now left that in garage to sleep over winter and came to UK and bought myself a 1.4 Jazz
And I must say wow what a difference in the smoothness of the car, the 1.2 engine I had was just so week compared to this, although there's only few horse power difference between 2 there is a really noticable difference.
I can cost in cities doing 30mph in 5th gear without it strugling, I can go up really steep hills on motorway in 5th gear, with the 1.2car I had to downshift to 4th . In city its much more responsive and when going up hills at city speed limits I don't need to downshift to lower gear as well.
What a Shame that I used to drive 1.2 for so many years and didn't knew I should have went for 1.4
Btw mine now is from 2004 , 1owner car, 105k miles, has passed it's MOT's for the life of it every time first time with no advisories in any of them, and is close to rust free and came with 1year mot. Have driven it for 3weeks now and the only thing that it has required has been 1new lighbulb, How much did I got it for??
wait for it... £400 ,came with the sunroof as well

Very pleased.
