Purchased pre-owned to replace XC90 which died. Low mileage example, super clean. Had to have the extra room afforded, but just couldn't handle the minor issues over the two months of ownership. Drove 6000 miles in those two months with dash and dash VIN rattle. Incredibly rough ride for a "luxury" wagon. Traded to a 4Runner and it has a smoother ride. After only two months simply had to give up and eat the depreciation. I avg 35,000 miles/yr.
Gas mileage was exceptional, averaged 24/25 with majority of highway at 80.
Ride comfort was horrible. Audio nuances, which I was accustomed to in my XC90 were even worse in the V70. No legroom in back seat.
