check for oil leaks... (peek under the car)
and check the axles...(turn the wheel to full lock and do circles... first to the right, then to the left... you WILL KNOW if something is not "right")
get the Vin and run it through Subaru to see what issues have come up with the car...
rare find you have there!
got some go-go power for a bigger car too!!
if it's a solid car, it could be a great purchase!
