If you're looking for an appliance, Camry is the way to go. It will be much less expensive to maintain than a Volvo. If you do get one of the Volvs have the radiator replaced immediately. They are prone to crack on the bottom and you won't know you have a problem until the engine starts making very expensive noises. I learned this the hard way. You'll also need to get the suspension bushings checked out and most likey replaced. The turbo is another possible problem area. If the previous owners changed the oil according to the factory schedule the turbos will easily last 300,000 miles. If not you could be looking at a very expensive replacement. Have a mechanic pull the valve cover and check for sludge buildup, which is a sign of improper maintenance.
I've never owned a Toyota so maybe someone with experience with high mileage Camrys will chime in with advice.
