Hi,<p>I am deciding on whether to buy an XC90, 2.5T, 5 seats, AWD from a friend, with 90K miles on it. I am interested in advice on maintenance costs, and general aging of the car.<p>The car has been bought new by my friend back in 2004. He has been servicing it at the dealer, and as far as I know following all the dealer guidelines. <p>I would like your opinions on what can I expect on maintenance costs going forward; I am especially interested in XC90s owners with 100K+ miles on the cars. <p>From what I am reading in the forum, some Volvos need extra maintenance when young; should I be concerned with even more maintenance going forward? With the cost of parts, and dealers, it could become a very expensive purchase. <p>Is it worth buying an extended warranty? Is it possible with the mileage the car has on it?<p>Thanks very much for your help!
