Don’t often see S63’s in my unicorn range, and here’s a pair that remind me so much (sadly) of Guenther, my first CarMax unicorn. Style, executive comfort, stupid fast for a 4,700 lb sedan. Ignore the bubble-butt trunk if you can. Both are 518hp V-8’s with Active Body Control (ABC), auto cruise control, and just about every option you could imagine in a $150,000 S-class. And as with my S55, these cars are outrageously expensive to repair (the ABC fails after 50,000 miles – $5-7,000 bill) and you don’t want to own without MaxCare, which makes them free (to you!). The 2010 is in Fredericksburg, Virginia (too close to home!) and the 2008 is in Los Angeles.
