Just got a 2005 Legacy GT with 204k mi for $1800. Took it to a shop for an oil leak, and it turns out to have a bad headgasket and also need new axles. Mechanic reccomends I sell it off while it still runs but I already really like the car. Id like to fix it and eventually upgrade and convert it to a manual but dont know if its worth all the money and effort, considering the high mileage.
