Used Kia hidden problems ?

So i am preparing to buy a used car on craigslist and want to make sure i wont get burned later on-
the car i am buying is a 2014 kia forte 31000 miles

we made a deal for 10,000 $ a good price !

i am wondering are there any issues that could be not initially noticeable during a simple test drive? i.e could it suddenly be junk at 35k because he did something crazy in it .

A few caution flags are that he is the 2nd owner after after 28k and does not know much about the car before that
he also was in a hurry when i first went to look it over but that may have been just bad timing
everything seemed to run well

we will do a much more in detail test drive and even a mechanic inspection before i buy -
what i am wondering is is there any way i can get burned even after an inspection with such a new car?
i also find it strange that it has not sold already but that could be just circumstance
he is not the best communicator but that may simply be that he is mainly spanish and i speak english - but he can text and speak in english to me.

just want to be cautious !
