When the 4th gen WS6 came out I knew I wanted a T/A WS6 at some point.  In late 2003 I saw an ad in automart that featured 2 WS6's - 1 Silver and 1 navy blue metallic.  Both were 02s, had < 10K miles, and were fully loaded 6 speeds.  Apparently, they were ordered by a husband and wife, driven for 12 months, then traded back in on matching Envoys.  I watched the dealers ad in each automart for a month and finally my wife said go buy it!  I sat in the showroom for 2 hours looking at the 2 colors trying to decide which one to buy as they were both the same price.  In the end it was my daily at the time and I did not think I could keep the NBM clean.  Paid 23,500.  Car was absolutely 100% stock when I bought it.
