Hello to all. I just purchased a mint 240D. It is a real gem. It has 150,000 miles on it and was really pampered by a doctor for the last 20+ years. He sold the car because he just purchased a 300d. (more power he said)The only problem that I have found with the car is the power antenna does not work and sometimes the central vacuum locks don't work. I noticed while driving the car home tonight that when I accelerate past 65 mph. I feel a tremble. Is this a tie rod problem or ball joint or something else. I don't feel it at all until I get up to this speed. Any advice is appreciated.
