A84.2 Year of construction 2004 -Question/Kaufberatung

Hello.

I'm thinking about giving up my D2 and taking a 2004 42, Q instead.
What are your driving directions with the car?
I sat in with a friend for a while, looked pretty good, but the old one was kind of more homey. In particular, the interior lighting (e.g.) air emitters and ambient lighting was better. Does anyone know if you can connect an MP3 player?
I'd love to hear your experience.

Thanks & Greetings
