Mine has a few noises but being a mechanic you kinda get an idea of what's just a noise due to being in a man made object travelling along at various speeds over various surfaces and what's a noise to worry about. Add to that the Micra is cheap although I don't think badly built for its price point and on the whole it's pretty quiet. In most cases you will know when a noise is one to be concerned about and you won't feel any need to ask anyone's opinion you'll just go straight to a workshop. If anyone thinks Micras are noisy go and have a drive in a Dacia or a Proton then get back in your Micra, you'll feel like you've got in a Rolls Royce!
