My Volvo V70 2.5T was delivered with two weatherstrips deformed and a noisy V- belt. They all gor fixed under warranty. The engine vibration is felt at idle and under accelaration. I think it is common for 5 cylinder engine (the Audi 5000 has the similar vibration). Once the engine is at cruising speed (~2000 rpm), it is quiet. The dealer service is excellence. It probably will be expensive after the warranty expires. The only anoying thing is the idle time before shut down the engine after a long drive (to prolong the turbo charger's life).
Safety, comfort, roomy, performance. It is built for the needs of family with kids.
