I found a 1993 Mercedes 300D diesel 2.5 turbo with 111 000 miles and I got seller agreed to $3300 dollars here in Chicago. It this car worth that much??? I drove the car and it drives good. No smoke might need tie rods in front makes a noise when you go over bumps. I drove it around block and the car was cold car transsmission shifted fine just I felt a little bump from first into second is this normal when the car is cold. Anything I should check before I buy????? Do this models have any unusual problems???? thank you all.
