Purchasing this vehicle this weekend. (Anything I need to know before I do so?)

So Im getting a 2008 Subaru Impreza Outback Sport with just over 180k miles. The car fax shows that the vehicle was very well maintained. Heres the car fax: https://www.carfax.com/VehicleHistory/ar20/U3gLHZOu9ceaennvM41SjUrZy49QbPkvkwIhYC1MTF8o1655DxnWOaCUksEGLnmJHuRj8RdRfh8QX_z6QhHMzEaGLa35kP8-TbM

It seems very clean as I took a look at it and test drove it and it seemed perfect. Drives as new. Heres the listing for the pictures: https://www.cars.com/vehicledetail/d7e827ec-5a69-4de5-a818-60cd3d103e4b/

is there anything I should worry about? I know about head gasket issues but from what Ive seen theres no leaks or anything worrisome. This is my first car so Im really excited but want to get a little more information on things I should be worried about. The dealership offers 6k miles/6month warranty which covered everything. but after that Is there anything I should keep and eye out?
