It's worth to get the KX-S if you could afford it. Among other thinggs, don't forget the KX-R is still having manual A/C and single disc audio. The most dissapointing bit abt the KX-R has to be the crappy audio. Yes, this can be easily upgraded and you can get a decent set that doesnt cost too much from JB Hifi, etc. but you run the risk of having the dash scratched. Same goes for other bits that can be upgraded, there's always a risk of damage from dodgy installation job.. There are some other bits that aren't easily upgraded, at least not cheap eg. leather sets, sun roof (grande), push engine start (grande), powered tailgate (again, grande). But if I can turn back time... I might go for the Mazda CX-9
