After 1997 BMW produced the stretch limo mor luxurious version of the 7-Series, the L7. Only 899 examples were built.

Since the start of production the entire in-car entertainment system is based on a very flexible automotive computer system. As a result the E38 models can all be easily upgraded with the newest BMW technologies including BMW's Bluetooth System, the DVD based Navigation system, as well as BMW's CD changers that play MP3s.
