Bought a CPO Volvo from them, second car I've purchased from Best Volvo. It's still under warranty. Since we bought the car, I've been taking it in to Best for oil changes. Twice over a 6 month period, I asked them to look at two other things:
1. Leaking coolant. I have to add coolant about every 2 months to make the add coolant light go out.
2. Rattle in the front end when slowly hitting bumps.
Both times, they told me both things indicated no problems. "There are no leaks. It's normal to have to add a little coolant now and again." They even said they were going to add some dye to the coolant to look for pinhole leaks next time.
And about the front end "our technician didn't hear anything abnormal in the front when hitting bumps."
The last time I went in for an oil change, they had a line out the door, and though I had an early morning appointment, I was asked to come back later.
So I took the car to a local independent mechanic for the oil change. I did not tell him anything about either of these two issues/questions. He got it up on the lift, looked at the wear on the tires, spun the wheels, wiggled them around, and told me my ball joints are shot. I moved both front wheels left and right to feel the play myself, they are clearly shot. Two seconds later, he tells me it looks like I've got a coolant leak. Sure enough, you can see the trails made by dripping antifreeze on the bottom of the plastic under the radiator. And if you look at the bottom of the radiator, you can easily see where it's coming out. Granted it's a slow leak, but if I can see it, I'd think a real mechanic should be able to.
I'll let you draw your own conclusions.
