I love the amount of room in my 300SD. im pretty tall about 6' and i have to put the seat all the way back to get a good stretch and when i have the seat that way with a buddy behind me they like that its very roomy. I know the w123 is alot smaller so room can get cramped if i was to have the seat all the way back with a buddy behind me.
Since it is an older diesel its much more loud then say my mom's TDI but Mercedes did a good job not letting in the sound of the engine in the car. Its pretty muffled down and i like that about the car. My dad loved the amount of speed and power in my car being that its a older and heavier diesel car but it will get you around pretty quickly compared to a 240D. I still want more power but thats just because im a teen
