I had just purchased a car but a month ago I was driving to lunch and I was at a stop sign when the light turned green I started to go the car started shaking and smoke was coming out of the front under the hood I had just an oil change so I took it back to the oil change shop. They could not figure out why the engine blew and I had to take it to a different BMW shop where I have to purchase a rebuilt motor and pay for the repairs. I can request all records from the automotive shop if needed.
