Last night the tensioner exploded and took the accessory belt with it.
This morning, I drove it to the 2nd closest repair place to my home. (There's a closer shop, just two blocks away, but this other one (Yuille Autoworks) has a good reputation for Volvo service.)
They just got back to me with the quote: $413 + tax.
I am gonna pay it, I just want to know if I am getting hosed!
