The maintenance history/notes of these Japanese imports must also be checked and researched. They may look mint from the outside but in some cases, a lot are hidden. We study and research the history of the cars that we import from Japan. It's a must do on any second hand car.
Sad to say brother, the Subaru that you have bought might have had 90,000 "racing" kms. When you got it, it might have been a ticking timebomb already.
We really shouldn't comment on the reliability of cars if we bought them second hand.
