What should I know

Swore id never have another car but I had heard realy good things about subaru. So when I found one with 100k miles for 6000 I jumped on that shit. So far i love it it handels smoth its comfortable to drive (im tall and hate most anything small). Im genuinely very happy with my purchas. But What are some things to know/wach out for on this bad boy. 2008 subaru legacy.
