I am looking at purchasing a Volvo 850, V70 Wagon and need some guidance as to what to look for and what to avoid. There are several wagons here in Southern California to choose from. I'm looking to find a 1998-2001 Wagone with fewer than 125k miles with good maintenance/ service records. What should I be concerned about in each car? What should I avoid? What about the difference between a 2001 V70T or V70R? ( there is one of each available locally, 79k and 109k respectively). I'm looking for some guidance here. Thanks!
