Do you put as much effort into your Car Audio?

No. Too much outside noise, inferior source quality except for CDs, too distracting for the driver, inhibition from playing realistically loudly (personally, I would be embarrassed to be playing loudly enough to disturb other drivers), cost I would rather save for my home system, and exposure to theft or damage from accident.

OEM has been fine for me, despite not having a Lexus with the Mark Levinson treatment.

Geez, Czarivey! That's a great story. You actually caught the guy.

I actually had an OEM radio stolen out of a BMW in Greenwich Village before they started employing scramble codes.

Glad to hear no one has reported an accident-related loss so far.
