By themselves, S550’s aren’t really unicorns ($35,000 or less, 60,000 miles or less) given that today CarMax has six of these on lots nationwide. Not rare. And this one technically isn’t either, with 67,000 miles. But rarely do CarMax S550’s drop below $25,000. Snaring an S550 for less than $20,000 is a deal. Of course, it’s only a deal with MaxCare bumper to bumper protection, because this three-owner model will be expensive to fix. I suspect the warranty will be offered to 125,000 miles, and five years from the date of sale.
And the warrant is CRITICAL for a 2007 S550 per Jalopnik and their piece “For The Love of God, Don’t Ever Buy A 2007 Mercedes-Benz S550” from 2016. Jalopnik warns that this model is cheap to get into, but has a little gear called the “M273” that will catastrophically fail and meltdown your S550 engine.  And that takes me back to the premise of the CarMax unicorn – with the MaxCare warranty I really don’t care if pistons explode through the hood into the night sky. Jalopnik warns that the cost of used replacement S550 engine with installation is around $6500. CarMax or Mercedes wouldn’t put in a used engine, so it will likely be a new engine and this car will run forever!
I don’t think you’ll find a more luxurious ride at this price. Find it here in Irving, TX – if the link is dead it’s sold, on hold, or being transferred. I suspect this car will move in days.
