make sure you bring a mechanic with you that nows subarus
what i do is go see the car and if i think its a good one and i like it, i then go and get a good subaru mechanic to look at it then.
there nothing worse than paying a mechanic to go see a car and it turns out to be a sh*t box.
put up a link to the car so we can see it, somebody might know it on here.
