TERRIBLE!
I allowed these clowns to change the oil on my German diesel. BIG MISTAKE. For some reason they charged me to replace my oil pan plug. Not a big deal...just a few bucks...I thought. But, when I took my car to the dealership for the normal service the dealership (who hires actual professional mechanics) said my oil pan needed to be replaced because whoever worked on my vehicle tightened the plug down with so much torque, there it was stripped and metal shavings around the pan and plug.
These guys are $9/hr jokes. Don't trust your transportation to them.
