The steering wheel pulls constantly to the right
The engine rattles in low revs
The clutch gives a fearful noise and has to be replaced soon
The interior plastics start rattling just after 3200 kilimeters...
The car looks nice.
The quality though is cheap all together.
Sounds like you received a Dud, I've never had a problem like what you are saying. Mine is extremely quiet at idle. Even blasted I haven't heard any "rattling" in the interior.. Sorry about yours, I have had mine for over a year now, and have had no major issues at all.
I am the owner of a Mazda 6 - Diesel as of December 2003.
At a mileage of 45.000 km absolutely no problems and only 2 hours in the service station for the periodic maintenance.
No spare parts needed except the filters.
