I've had two major repair jobs done here and both made me a bit uncomfortable, so I'm not planning to return. Their only diagnosis tool seems to be the computer reporting tool, This leads to things like wanting to replace an entire part of your car (the entire ignition system, transmission, etc.) if they can't identify a [trivial] problem.\n\nWhile they've never done anything that made me suspect they were suggesting things to run up my bill, it seems more like they don't know how to diagnose the specific problem and just 'ripp it out and replace it all' is their modus operandi.\n\nTheir prices are on the high, as well, to the point that they actually 'threw in' some free repairs that I know to be nontrivial after I complained about the amount I'd spent and still didn't have a working vehicle.\n\nLastly, service is extremely slow - both jobs I had them do my mechanic back in TX could've done in a few hours, instead it took them overnight (and I dropped the vehicle off in the morning both times).\n\nI tend to keep my one star reviews for outright scams/food poisoning/etc. -- my review of Big O is just barely above that line.
