my o2 sensor was just replaced at 85k miles (US) for $236.43 parts and
..8 hrs labor @ $81/hr= 64.80 total $301
but this was not at a volvo dealer. you may have a good price there.
hasn't happened here
same here oops no that was on my ford escort wagon
or broke (money and car)
likewise. need to have confidence in that repair place.
where are you located (I presume usa)
