Unfortunately, you're in tough spot with this car. There's no getting around a few 2.5 hr drives to your dealer and yeah, they're not going to work with a local mechanic to get your car fixed. Good or bad, your dealer has probably done a few of these so I wouldn't trust it to any indie shop. I wouldn't expect a lot of goodwill from Volvo (or any) as I'm guessing you don't service the car with them. I don't know how much just owning a few Volvo's counts towards goodwill - probably not much.Has anyone paid out of pocket for just new piston rings at an independent shop?
