I got all misty eye'd replying to a thread about mileage and remembering that 1st drive home with my new baby girl back in 2004. And that's not even my coolest memory in an E53!
What's the coolest thing you remember experiencing because of, inside of, with the help of, or just because you happened to be there with an E53.... ? No limits.. Share the happy times.
Nearly 20 years out from the final production, we need some happy. Give!
