Urgent help needed with my 1983 240D. I was driving on I- 395 South in Washington D.C. last night around 4:00am doing about 85mph. I felt a big jerk like I hit something. I though I had a flat tire till I realized the car had cut off. I pulled over to the me side of the road and the car would not crank. So I called AAA they towed the car home. When I inspected the car this morning I saw nothing obviously wrong. The main problem is I was suppose to drive to New Jersey today on business. Plus I just moved to D.C. two weeks ago and have no clue of a reputable mechanic to take my car to. I know the information is very vague but any help would be appreciated.
