Did a successful system install in my 300E only to end up totalling the car a couple of years later!
So I pulled the audio components out of the vehicle in the hopes of reinstalling in a future car I have yet to purchase.
Bought my daughter a car with the money from the insurance settlement, and she has wanted me to put the stereo gear in HER car!
Told her that I didn't want her having that kind of distraction in her car while she was still new at driving, but I would hook her up in a year.
