KIA cee’d 2.0 CVVT – timing belts and more

Hello everyone! I have an offer for a used KIA cee’d 2.0 CVVT xR, BJ 2009 and I have two questions: 1) I have found no definite information regarding the change of timing belt, therefore: Can someone say with certainty at which intervals (years or KM) the timing belt is to be changed? 2) What should be paid attention to in general with a used cee’d? The last one I looked at, despite low KM performance, already had visible rust appearances on the chassis. hurry up the rear axle, is that normal at cee’d? Thank you!
