Anyone have any comments, rants, or recommendations about any Mazda service depts. in the DFW area? I'm having a problem with the turbo not spooling up. I'm assuming it's just a cracked/loose pipe. But I was planning on bringing it in to have it looked at/fixed. I was just going to go back to the dealer where I purchased my car, Hancock Mazda(Mesquite, TX), but I wanted to hear some opinions first.
