Overall a short-term reliability would be probably higher, but long-term P3 rust way more and uses made in India SKF bearings everywhere. As a P2 owner you'll be facing "strange" problems, like need for the rear differential rebuild. SKF Sweden bearings in P2 almost never die.
I've heard that P3 has also more reliable suspension, but what I see is sagged springs in just 3 years.
Not to tell that the Vehicle Communication tab in VIDA is about twice bigger for P3 than for P2
I decided to break up with Volvo and got a non-Volvo recently as a third car. Will run and repair P2 as long as I can.
