My engine coolant was leaking. They found the leak and I asked them to change the oil while they were at it. The previous 'good deal' oil change had done shoddy work, over tightened the oil pan plug, that promptly stripped and broke. Oscar fixed the error(shortcut?) the other garage had made, and replaced the radiator that was leaking. I found Oscar very knowledgeable and confidant about what was the problem, what possible repairs where available and what the best/cost effective longterm solution was.
