CX-7 was discontinued after 2012 and replaced with the CX-5, which has received great reviews.
CX-7 was also available with a NA 4 cylinder that got better MPG (27/20) and the expense of the HP of the turbo (24/18).
Used CX5 is going to be just over the $20K mark. They're selling very well, but few are available used.
My wife really wants a CX5 in blue...
