I don't understand where you keep spreading this sentiment when the data doesn't back it up.
I just ran a quick check on KBB comparing 2013 CX-5 Touring and 2013 RAV4 LE (similar starting MSRP) with 70k miles and "very good" condition. The CX-5 actually came out quite similar in private party resale value.
CX-5: $11,100 - 13,100
RAV4: $12,100 - 13,600
Having just searched for an SUV for my wife in that year and price range, I can attest that the bulk of compact SUVs of that ilk from just about every manufacturer fall into that price range. It's no secret that cars lose about 20% in their first year and 10% every year after that, which matches well with these numbers.
