That is one detail I forgot too mention. The gas mileage is better on the Volvo XC70 than it was on the much smaller Subary Legacy LS. The cost of ownership for the Subary was much higher than my XC70 since the maintenance, fuel and depreciations costs were all much higher.--Cheers, Steve Henning in Reading, PA, USA .
