Welcome to the ‘elite’ group of 240D owners and welcome to the forum. I got my first MB (’81 240D) a couple of months ago. I love this car!
The people on the forum can be VERY helpful. I like to lurk around and learn as much as I can and post a question here or there. To keep some of the folks off your back, be sure to search before posting a question.
Other than that enjoy your new toy!
