My daughter took her car in June to get an oil change was promised it was done. She returned in July to get a complete overhead job done and paid 600-650, which included an oil change, she returned a week later because the car was running hot and was told my car could not be diagnosed because the technician that performed the original work was off that day. I returned the following week (after numerous calls), but this time the car was overheating and it was shutting off while putting the car in reverse, we checked the oil and it had a lot of grit and deposits in it and the oil was very dark almost black. She was told they would do another oil change and check the car for problems. She left and one month later the car would not start. The car was towed back to NTB because we thought it was the overhead leaking. Upon being checked, she was told by a different NTB that is was my oil pump and this caused the engine to blow. My daughter is diligent in keeping the car tuned up and changing the oil frequently. Now the car had to be towed again and a new engine installed. PLEASE DO NOT VISIT NTB FOR MAJOR MECHANICAL WORK, they are a rip off.
