I have located a 2001 XC V70 for a song, and it has a perfect service history with a dealer. I'm very impressed with the condition. It has 116K miles. <p>I am concerned however how much this car is going to cost me to own. I currently drive a Mazda 3, which I bought after I bought an S40 T5. The S40 was quite an unreliable car. I have not had to do a darn thing to the mz 3. <p>I can essentially do an even trade with my Mz3 on it. <p>What should I look out for? Is this an expensive car to own if it's been very well serviced in the past?
