What is the last thing you would expect from the classic little Honda S600? Acceleration? Burnouts? Extended wheel base? Yeah.

Mercedes-Benz's current global advertising blitz uses the tag line -- "the best or nothing." I'm not going to go into the details of why Mercedes-Benz isn't the brand juggernaut it used to be, but I think that used Benzs should use the slogan "the best for nothing".

Somewhere between the cute 'n' tiny Honda S500 and the later (and more common) Honda S800 lives the Honda S600. It was the first of Honda's S-cars to get a hardtop version, but still featured a roller bearing 600 cc 4-banger and a chain driven rear end.

Of the two cars with the name S600, one was a '60 Japanese 2-seater with a glorified motorcycle engine and the other was a 2000s Teutonic two-ton monster powered by a twin turbo V12. Strangely enough, if you find either with close to 200k miles on the odometer, they end up costing about the same...in initial purchase price...true cost of ownership will vary.

The Honda S600 was the spiritual successor to the S500 (Honda's first production automobile) and survived for three years (1964-1966) before it was replaced by the S800. You don't get to be one of the top auto manufacturers in the world without building some great vehicles and the little Honda was a great alternative to some of the small displacement British and Italians from the day.

The mighty W140 Mercedes-Benz S-class was the last of the over-engineered Benzes with a reported development cost of $1 billion. The W140 introduced the world to features like double pane window glazing (regularly and erroneously reported as bulletproof) and motorized closing doors/boot latch. When new the S600 could cost in excess of $140k but today costs as much as a used Honda. Find this 1999 Mercedes-Benz S600 V12 W140 for sale in Chandler, AZ for $6,200 via craigslist.

The Mercedes-Benz W140 series S-Class was the result of a decade of German engineering development, with cost overruns that allegedly leading to departure of Wolfgang Peter, Dailmer's chief engineer. The resulting car is a pinnacle of over engineering, over achievement and overall awesome, especially in the S600 flagship.
