No defects found.
Car handles very well.
On rough chip seal roads, the interior is so noisy that it is difficult for driver and front seat passenger to converse.
On any surface other than smooth seal, the ride, especially in the back seats, is both rough and noisy.
Cruise control is jerky and severe on undulating ground. It overruns the set speed by 8-10 kph before settling back.
Compared with your Camry the suspension setup is for nimble handling rather than the Camry's Touring style "float" type suspension setup hence the difference. It's all down to preference really, plus the low profiles on the Mazda don't lend themselves to noise reduction or a bump free ride.
If you're after something with a higher lateral G rating, faster slalom speeds and faster turn in and cornering stability the Mazda 3 is more for you.
If you're after a softer floating type ride which soaks up bumps and lends itself to quieter touring the Camry would be the better choice.
