used 2018 Forester Premium questions

looking into purchasing a used forester. currently i am looking at two 18 premiums but a bit concerned at their price for the miles they have. one has 67k for $13.9 and the send has 91k at $12.5. from looking around this price seems low compared to others and im not sure why. the 91k mile one also has been on their lot for 10 months with $2.5k in price reductions. do these prices and lot life show concerns for me to possible stay clear of these? they both look great online but haven’t seen in person. i appreciate any and all insight anyone can offer cause i have never owned a subaru. thank you!
