hi guys. im considering a 2014 used optima k5 (facelift version). is there anything that i need to be concerned of? potential problem?

currently im driving a proton persona, and my wife just bought new kia k2 sedan. very impress with kia, so considering to change my proton to kia.

thx guys. im looking at the facelift model year 2014, should be covered under warranty (if the owner follow the service schedule). price below 100k. so the steering rack and air cond is manufacturing problem or wear and tear prob?

How about fc? Driving experience? Can share a bit about what should i expect. Also abit comparison with other similar segment car. Ive yet to test drive k5, but will find some free time to drop by nearby showroom for a quick test drive.
