New to Subaru. Legacy advice please

[JABB]

Looking at a 120k Legacy 3.0Rn touring, and coming from a BMW 320D.
I am down grading to free some money.
Is this a good car, and is 120k getting on or do Subarus do the miles well?
Anything to add would be more than appreciated. I have heard the 2.5 can be problematic with head gaskets and cam belts. Am I right looking at the 3l?

Thanks V
Anyone near Woodstock / Chipping Norton / Banbury who could show me around one?

Would you guys consider a 3.0 with 170k on the clock if fully maintained?

Sorry, looking for the estate version
