I'm currently considering a v70r awd for $3995. The car is at a dealer and appears to be in good condition. This will be my first actual volvo (own 2005 ford 500 which is based on volvo chassis but with ford engine) I am able to do my own mechanical work and have done some research. The question I have is: Is the AWD system truly as prone to failure and expensive to fix as the internet would have me believe?
