Had engine problems, they recommended me spending $3,400 on a remanufactured motor with 75,000 miles on it. Seemed cool til I noticed they put old burnt out plugs and wires and other old parts on a great engine? Now I'm spending another $1000 on parts and labor less than 6 months later.. I asked Pohanka Nissan to change out old spark plugs while they had the engine out and they didn't. Yet charged me soo much. Why put bad spark plugs into a new engine and expect the engine to perform accordingly...???
