I was wondering if anyone has heard this. I just bought my CX-7 a few days ago and I got a call from the salesman from my Mazda dealership. He said he wanted me to bring in my CX-7 to run some quality assurance tests. He said that Mazda likes to test the cars within 7 days for quality assurance. Has anyone else heard of this? If so, what kind of tests did they run?
