There is a local 1987 420SEL for sale for $2995 OBO. It has 178K miles. I have not seen it in person, nor have I driven it, but I am wondering initially- does this seem like a good deal? The car is gold and the paint still appears to gleam. It has new tires, CD player, 100% rust free and supposed to run good. What typical trouble spots do these cars have? They also state that this car gets 23MPG (does not specify city or highway). Does this seem about right? I really want a 81-85 300SD, but I really like the styling on this car and it seems like a good deal to me. Thanks in advance for any information.
