Howdy ya'll.... My wife is really wanting to get a used CX-7 and we test drove a couple yesterday.
First was an '07 turbo which was nice

Second was a '10 regular, and we like the '10 better, but it seemed to have a roaring noise that the '07 did not.

I'm kinda gun shy about noises, so I wanted to come in here and ask if anyone knows of a history of 'roaring problems' on the CX-7's?

Which one was the norm, 'roar' or 'no roar'?

TIA

Welcome to the forum!
My motto: the simpler the better. No turbos for me.

I have not driven Mazda 7 in any form. But i have driven some vehicles that roared. It is important to know what causes the roar. Is it an engine roar or road noise? Engine roar would increase with the rpm's and tire noise would increase with the vehicle speed. The last vehicle I bought was roaring as well but only for 1 week. After I put new tires on the roar was gone.
Go back to that '10 and check the tires more closely. Run your hands over the treads and feel for saw tooth effects and other signs of uneven wear. If you find uneven wear you know it's the tires and you negotiate the price lower. A decent set of tires and wheel alignement will set you back about $600 to $800 bucks (ball park figure).
Better yet, have it inspected by a mechanic of your choice prior to purchase. this ounce of prevention may cost about $100. But it will be well worth every penny and more.

 

Definitely check out the tyres. Also on the turbo model, make sure it has a perfect service history, these engines don't like missing services.
