I took my car in once for engine knocking noise. Firstly they came up with engine block is screwed up. Then they asked me to change all the plugs and wires. After wards i get a call that oil pan needs to be changed. The total repair cost 1500 bucks. The car is not even worth that. Took my car back and took it to my mechanic. Got the issue resoloved and he said plugs wires are fine. Only need to replace bolt on the oil pan. Very unhappy with them.
