Hey all..

I have a pretty noobie question but would help me a lot!
Basically I just purchased a 2002 Subaru liberty at auctions.. And it was advertised as a 2002 heritage 2.5 litre model etc. After looking at it in the flesh and being excited about it all. Bid and won. All was happy. Now in retrospect looking back at it, I'm having questions if it actually is a heritage model. And worrying even more about the size of the engine, if it's even the 2.5 litre model...
Is there any tell tale obvious visual differences between the various 2002 liberty models? I'm quite noobie with cars, so am not going to know much differences by looking at engine bay/ unless someone can hopefulu point me in right direction?
The differences I've noticed looking back is it doesn't have leather seats, doesn't have leather steering wheel, doesn't have heritage badge on back? Doesn't have wood grain interior highlights..

I'm aware I might be freaking out for no reason.. But thought I might check with the experts!

Thanks so much for any help..
