I am looking at a 1972 220d w 150000 miles. I was wondering what I should look for. The owner said he was the 3rd owner no rust except rear floorpan behind drivers seat. Uses about pint of oil every 3000 miles (oil change interval). Its a 4 speed and shifts fine. Motor has some blowby but he said not alot. He just put on new tires ,brakes tie rods and a alternator. The interior is good with only a 4 inch tear in the front seat. I have been looking for a 240d but this one came up for sale. Any help would be appreciated. Also are there any major differences between the two other than the body? Thank you.
