We recently purchased a 2005 V70 used with only 50000km on the clock. We traded in a our 2006 Pontiac Montana SV6. Our kids were initially disappointed to see the van go, but once we started our vacation with the V70 they were very happy. Seats are way more comfortable, and with the integrated child seats they actually have more rear seat room. We like to cost of filling up compared to the minivan, about 30% better fuel economy, and we are comfortable in Volvo's awesome seats, and the dual zone AC keeps up both happy in the front as we can adjust to our preferences. We recently did an 900KM long weekend trip, and every left the car far more refreshed and relaxed in the Volvo versus the minivan.
Love the seats front for us, and the integrated back seats for the kids. Great visibility, and a true highway cruiser for long trips, and the cargo area is huge and handles whatever we throw in it. The front console and controls are well laid out, easy to use, and actually make sense.
Could use more pep in the base version, but it is great for traveling with the kids, not a speed demon but gets you around just fine.
