We purchased 2 XC70s over a year ago and have only excellent things to report. Purchased the ext warranty on both. Had a problem with the transmission on one, but the dealer stuck with the issue and eventually changed the entire transmission for a new one, not a rebuild. Since then we have clocked over 50K each on both vehicles and have only had routine service done. I have run through snow so deep that it was at the top of my tires while hitting remote areas for cross country skiing and snow shoeing. Cars sit out all winter and both start at first crack of the key. Winter temps of -28C so far. A/C works great, sometimes above 40 C in Kamloops' summers.
Seats are incredible on long road trips. Stereo (dolby centre channel) spectaclular. Gas mileage is running about 10.5 avg l/100km both cars. Just had a mazda 3 for a week with auto tran/ac it got 9.9 for same type of driving. Love all the storage pouches on seats and under rear deck.
Alloy wheels don't clean up very easy. Better design would allow easier cleaning. Love the heavy plastic body armour... fends off rocks and winter sanding.
