Well, you've heard from an owner who likes his CX5, from a guy who likes GM products, the man who runs this site and has a lot of data on the car you mention as well as all its competitors, and a couple others. I happen to own 2 Mazdas and would buy a third if the need were there. I also have owned plenty of other cars, four currently. I would agree that there is nothing that should prevent you from buying the CX5, it drives and looks better than the rest of the reasonably priced SUV's of its size. I just bought a Mazda 6 and really like it.
The reasons not to get the Mazda might be its resale value in a few years, compared to CRV or RAV4. But you also have less invested up front. Put the few thousand dollars you saved on a Toyota in a mutual fund and sell it when you sell the Mazda, and i bet you come out way ahead. Also the service from the Mazda dealer vs the Chevy, Toyota, Honda, etc. If that matters to you it might be an issue. Since your new car is under warranty you might see the dealer a few times in the next few years. The more I mature, the less I have patience for an for an inept dealership dealership.
Last reason would be to not upset Norm. Mazda has nice products, I hope they can make a go of it now that they are on their own, and not being a part of Ford. I'd get the CX5.
