VIOC has done okay for me. I have them change the oil in the wife's Fusion. I don't want to have to dig out ramps to get under the stupid car, so they have done it since it was new. I pay attention, but so far so good. Their computer systems are not accurate, like miles between tranny service, and it always recommends a rear differential service, which doesn't exist on the FWD. The sharper guys just laugh it off with me because they know.
That being said, I wouldn't send my wife or daughter there alone, or to any of those places.
