I don't know what to do - I am looking at buying a used V70XC (good price of $3500 with 119,000 miles). Known problem is an oxygen sensor, and I am going to have a dealer do a full check of the car, but having read all about the problems I am worried. Consumer reports lists it as a car to avoid. I am used to a 240 - mine has over 250,000 miles now. I have driven 240's for over 20 years. I will not be happy if this car is a money pit where only a dealer can fix it. I usually use an independant mechanic. The seller has some records of service at 90,000 miles, and at 111,000 he got the timing belt and water pump replaced, which in a 240 is the big expense. I prefer a wagon. Should I just keep looking for an old 850?What should I do? Help!!!
