Do you mean a 300E sedan or 300TE wagon?

What do you need it for? What features are important you or do you definitely not want (e.g., can't get that year/model of MB without leather and without AT)?

Do you ever need to fit 7 people legally in the car?

Do you DIY? Do you need advise on which is easier to service yourself?

The 87 300TD is the best wagon ever sold in the US
