I've had a mechanic for a while that wasn't too bad. But after taking my ML55 to him a few weeks ago, I've become a little leary. He seems to want to replace everything in site and doesn't necessarily know these specific trucks that well. Anyway, I was wondering if anyone has had good luck with any independent mechanics in the Chicago area. I'm less about trying to save a buck as having someone who knows the type of things that go wrong and fixes them without a lot of drama.
