Hi Paul,
That sounds great (pardon the pun!).
Luckily for me, mine came with the B&W system and it's stunning. I'm also lucky enough to have a B&W / Musical Fidelity system at home.
However, back to cars...
Have you done anything to improve the dim/yellow old interior lights (replacing them with LEDs)? If so, was it difficult?
Cheers,
Jon
