I generally go here because it is convenient, and i've never had any issues before. I can't say for sure, but i think they overfilled my coolant leading to a radiator leak. I went there for an oil changed, during which they told me my coolant was getting a bit low and they could top it off. which was fine with me, but shortly after i sprung a sudden radiator leak. Note i had driven very little between leaving there and getting the leak, and no problems were presenting, so my mind is inclined to connect the events, but i can't be sure. So be wary, and double check your fluids after they get done, just in case.
