I don`t know of any advantages, except a yr newer. but it has some things that are only for that model yr. If it is some what like my 300D, the air filter, starter, down pipe are different for this yr and cost a little more.
85 was the last yr for the w123, not sure if 85 was the last yr for the w126 with the 617 engine. the trap oxodizer has to be replaced every 30000 miles unless the up grade was done. I had MB replace ours when we first bought ours. it had no power, and had gone over 50000 miles and was plugged up. at that time MB replaced these free as part of the warranty on the smog stuff.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
