I’m a fan of the 2006 S350. It’s a one-year-only and final-year W220-generation S-class that features one of the most robust powertrains available in a modern Mercedes: the 3.7 liter, 240 hp M112 V6 paired with the 722.6 5-speed automatic.
Legend has it that Benz brought this variant over to The States to help quell ongoing reliability concerns stirred up by its V8 counterparts (S430, S500, etc.), which were mostly then equipped with the brand-new 722.9 7-speed gearbox, which was having some teething issues.
As a standard-length model, it also has better proportions than its V8 brethren, which are all riding on a wheelbase that’s been stretched by about five inches.
This example looks to be well-cared-for with lowish miles and just a single Arizona owner. At $9000, it’s not the cheapest W220 you can buy. But it will likely be one of the cheapest to own in the long run. And it’s certainly a hell of a lot of car for less than ten Gs.
Offered on craigslist HERE by a private seller in the Scottsdale area. It’s been listed for about three weeks now, so if it’s still available it might be a good time to make an offer.
