I have owned large cars all my life, Panthers (Crown Vics, Marauders, Towncars), W126 Mercedes, 7 Series BMWs (E38) etc. When the SHO came out, I was driving AWD Five Hundred for a daily driver. I had bought this hastily to replace a 22 year old Mercedes that had turned 300,000 miles and was starting to have transmission issues. I liked the D3 Chassis and the amount of room that the Five Hundred had, but the power was a little lacking.
I was actually shopping used 300C SRT8s, Base G8 GTs, and the 4.6L Genesis. I drove a few SRT8s and liked them, but the 12mpg was scaring me away for a daily driver. The G8 GT was nice, but I felt that the switchgear/interior stuff was not near as nice as the 300C or even my Five Hundred. The red lighting was not liked either. I shied away from the SHO because it was far above budget than anything else I had in mind, but once I drove it, I knew that was the one. I ordered in Oct 2009 and it showed up Feb 2010. Went into the shop 3 times, the third time I never got it back. Replaced with a 2011 SHO. No problems to date!
