Rod found a 5 series on ebay for super cheap.  It's been a solid, reliable car, despite a bit of abuse from the prior owner, just scratches and chips, broken fender liners, 'funny touch up and repaint stuff.  Overall a good looking car, with the factory sport package and a quiet but sporty ride.

This is the perfect place for a couple of really nice big Focal 13" Polykevlar 33KX subwoofers:

This shows the subwoofers, freshly mounted in a custom painted and clearcoated fiberglass enclosure that Rod built and finished.  The rear trim panel is wrapped in BMW vinyl to match the interior, and there is a similarly wrapped flush panel in the tray with the amps.  A bit of embossing of the shop name resulted in a faint image in this photo.Below the "shelf" the subs sit on are a Kenwood Music Keg, Kenwood navigation unit, and on the motorized drawer sit two Audison amplifiers, shown below.

This is how it looks at night (or with the lights out, as in this photo) with the drawer extended, before the rear trim panel was fitted.  The Audison logos on the amps were originally blue, and looked sharp, but didn't match the amber interior lighting and orange neon in select parts of the trunk.  The LED's were swapped out, desoldered and replaced with new orange LED's, soldered in place.

This is a mesh covered opening that was made behind the rear armrest, to allow the subs to freely vent into the interior cabin.  The stock rear speakers were also removed to allow more 'breathing'.  Neon was placed in a few places and a red voltmeter displays at the bottom of this opening, though it's hard to see in this photo. With the armrest up, this is hidden.

In order to install a Focal Polykevlar 3-way component set, a floor "pod" was fashioned for the 6.5" woofer.  The mid and tweeter are both mounted in the front doors.  They, along with the 13" Focal Polykevlar subwoofers, are driven by a pair of stout VRX Audison amplifiers.

This poor quality photo shows the KVT-915 Kenwood Excelon indash unit, showing off the TV tuner.  This unit processes CD's at 24 bits, as does the Music Keg by Kenwood, with an 80 GB Phatnoise hard drive cartridge.  With over 200 uncompressed CD's, the ability to listen to DVD Audio through the indash unit, 100+ channels of Sirius satellite radio, AM/FM stations, CD's, broadcast television, there are many listening and viewing choices available.  Whether it's a demo CD that shows off the rich dynamics of the system, NPR, 70's or 80' music or anything else, with 1500 watts and all true high end components from quality brands, everything sounds pretty good.
