Curious what you all think a fair asking price might be. I'd prefer a private sale, if possible.

The Basics:
Original owner (purchased with 8K in 2004...formerly AoA Exec car).
<73K miles
Exterior in very good condition
Interior in very good condition
Non-smoker
Garaged
Detailed 2x a year
Dealer maintained up until a few years ago
Avus Silver
Black interior w/ silver piping
Carbon trim
SE Exhaust
Cold and Warm Weather Packages
DRC upgraded (v2)
TC rebuilt

Upgrades conveying:
RNS-E (latest version) - Original radio will convey, also
Bluetooth (doesn't seem to be working)
Dice iPod Connector
Current SiriusXM module

Optional upgrades to be removed or negotiated into sale:
Eisenmann Exhaust (cat-back)
Sportec (non-catback) - NIB
Set of Ronal Wheels w/ snows
Set of 20" Sportec Mono 10s. <200mile Michelin Pilot Sport Supersports.
Dahlback air intake
Winter/rubber mats
Inexpensive set of RS6-badged mats
Spare NIB aftermarket front rotors and pads (cryogenically hardened at 300below.com)
Spare used front left headlight ballast (never installed)
2 spare tires (one OEM 18" size Pirelli, the other 255 Bridgestone for 20" Sportec Mono 10)

Car was just serviced (oil change and alignment) by local independent with good reputation (75K is the next big service due). Throws no codes. As far as I know, everything is in excellent working order (although, center armrest lid needs repair). No warranty. Located in the Mid Atlantic.

Any guidance is appreciated.

TIA,

CW
