The Mazda CX-7 uses the Ford C1 platform. It was developed during the time when Ford still had a major influence on Mazda design. 

While I’m not to familiar with this specific platform, I’m not a big fan of Ford. Unless some else has good personal experience with this, I’d say to pass on the CX-7.

I’d be more open to Mazda’s developed after 2011.

And super open to Mazda’s developed after 2015, when they struck a deal with Toyota.  

Nah I'd pass, Scotty said he had a customer with one that fell apart. On the other hand, he said the CX-9 was decent. CX-7 is different though. For the price I'd look at a 2007 or so Toyota Highlander.

Its a 10 year old vehicle with Ford parts, so 6k is a tiny bit much.

If you want to look into it, have a mechanic check it out before you buy it.
