I'd look at the pedigree. Just like when buying an expensive dog.
See the cx5s direct ancestor is the MX5; thus the similarity in the name. It comes from a family of performance cars such as RX (7) and Cosmos. The CRV ancestor is a civic wagon and a prelude. Thus the cx5 is the sport coupe of the cuvs while the crv is the econobox of the cuvs.
Compare:
Cx5 pedigree
Mx5 1990
Rx7 fd 1993
Crv pedigree
Civic wagon 1989
Prelude 1992 "FWD"
When i get to a computer I'll show you guys the pedigree first hand.
