You should look for a good independant Volvo mechanic - some are old Volvo techs - experienced and good.

Ask this board for a reccomendation - post where you live.

I purchased a used XC70 and found that Tom's Garage had serviced the car.

I did a search for Volvo mechanics in Massachusetts and was surprised ti see quite a list of shops in my state.

Tom's was on the list and I was able to talk to him. I found that he had not been allowed to change the brake fluid or put new spark plugs in. I had those things done at my next service.

I am very leery of chains. Without my knowledge, my daughter took her 740 to Jiffy Lube and they bent the lock on her car's transmission dipstick tube so that they could check it faster. The manager admitted it to me!
