As long as you use the correct oil type it should be just fine. The rocker arms don't tolerate cheap oil. If it doesn't have a tick at idle it is probably fine, just don't cheap out on oil changes. The transmissions in them is not the strongest but it will last forever as long as you don't haul or tow a lot of weight and don't abuse it. My neighbor has one and it has well over 200k miles on it and has been mostly trouble free with just a few minor things over the years.
I would rather have a Dodge Journey over an old Kia or Honda any day. Any old car will need worked on occasionally and parts availability is way better for Dodge for the oddball and uncommon things that tend to break on all 10 year old cars.
