Not a fan of the 15 look and deletes compared to the 14, but depending on when the car was sold new the 15 is the more logical choice warranty wise.
Water pump were about what's left of the major issues. Not sure if the cam cover was revised as well when they redid the oil cap and filler neck.
Yes, both were revised, but both still have issues.
OP - service records are a good thing to look for with these cars. Make sure oil changes were done on time. Look for any history of overheating, etc.
Run the VIN and make sure there are no outstanding recalls like the brake booster vacuum pump switch.
If the car has over 45K miles on it, it should have the transmission fluid flushed. If it has over 60K, add spark plugs to the list - and be very careful taking the ignition coil off, as the boots like to break. If coolant in the expansion tank looks low, water pump and other coolant leaks are relatively common.
