Would you recommend getting a 2016 Mazda CX-5 base or a 2015 Buick Encore base??

This should help you, see this attachment.

Mazda is the 2nd rated top car, see this link. http://www.cheatsheet.com/automobiles/5-car-brands-to-buy-and- 5-to-avoid-from-consumer-reports.html/?a=viewall

Since the Acura RDX was not mentioned (pricey) I would go with the Mazda. A Consumer Reports review would not put much weight on my decision to buy a vehicle. I like to look more at individual owner's comments and talk to actual owners if possible. Do some additional research.
