Had it 1K miles so far. Solid build. Nice ride. Great seats. Nice stereo. Quiet. Reasonably-priced luxury. Beats my old SUV in every way. Getting 21 mpg city so far. As for models I didn't buy: Audi A4 Avant was gorgeous but had terrible rear-seat legroom and bit of road noise. Passat wagon had lots of road noise. V70 won out on those counts and others. Also, it has 5yrs/60K full maintenance. My only beef: It was scarce in my area, so I didn't have many color choices. Scarce because Volvo would rather sell you an XC70 or 60 (for way more money); also most V70s are a factory buy, apparently. But V70's mileage is better than the XCs. V70 is sleek, solid, luxurious ... the quintessential Volvo.
Seats. Bluetooth. Stereo. Smart key. Parking sensors (more handy than I would've imagined). Seat heaters, and the ton of heat/defrost ducts thruout. Blind-spot system. PZEV rating. Daughter loves the built-in booster seat. Car's design is elegant, both inside and out, with many thoughtful details.
Mileage could be better yet. Rear-seat legroom could be better yet. I wish it had the A4's panoramic sunroof. The digital gas gauge leaves me a little cold, and I feel naked without a heat gauge. I wish it were a bit more nimble to drive, but it's not a sports car -- for a wagon, handling's great.
