In the market for certified used 2015 CX-5 or 2012 CX-9. CX-5 sport has 56,000 miles asking price 17,897. CX-9 sport has 49,000 approx. miles and listed at 15,987. Both seem to be good deals and this would be my first Mazda so looking for input on common issues, the good, the bad, the ugly. I can give more info on specs, but wanted to start with a general inquiry and go from there.
