I just measured.  Both front and rear at at 4/32" remaining (measuring actual tread, not the deeper water channels).   Sorry, I'm not considering vehicle trades at this time.

*** Update 2014/06/30 - price lowered ***

Beautiful but not flawless. See computer warnings in last photo for catalytic converter light, broken tire pressure monitoring system, and parking lamp. Maintenance is not cheap so please be sure you know what you're getting into.

I've stayed on top of the major maintenance: Transmission oil and single-use pan were flushed and replaced at 100k miles. High pressure fuel pump was replaced in 2012. Spark plugs, ignition coils, and fuel injectors were all replaced at the same time as the fuel pump.

Car is loaded with comfort seats in front and in back, adaptive cruise control, suede headliner, 6.0 Liter ~430 HP V12. Heated and cooled seats x4, massage front seats, cooled cup-holders. Two built in refrigerated compartments, including a champagne cooler between the rear seats. Was ~$130,000 new. Actual gas mileage averages ~16 in city, ~22 highway

Priced at $20,749.00 USD worth of BTC.   Will (slowly) lower the price until it sells.

You can create a bitcoin address completely offline, and bitcoin can be "sent" to it.   There is no location information encoded into the address itself.

Bitcoins only ever /exist/ as public knowledge on the blockchain, and are associated to new addresses by being signed over to new addresses from their previous addresses.   It's like a giant public ledger.  In this way, the coins are never stored in your wallet.   Your wallet just contains the necessary information to sign transactions involving your addresses - e.g.: to spend your bitcoins you need information that's private in your wallet.


This example doesn't quite fit your first question.  Because of the public nature of the blockchain, it's fairly easy through analysis to determine which addresses belong to major websites like mtgox.  

Per the feedback solicited here: https://bitcointalk.org/index.php?topic=364353.0

bitcoin-qt 0.8.6 is functioning fine on my OSX 10.9 box (upgrade from 0.8.5.)  I haven't experienced any of the db corruption problems issues on this node before, though.

Cheers,
