Jeez, as an engineer, I am still amazed at some recent engineering solutions. This seems to be such an archaic application, that I would never consider a newer ML Bluetec! Imagine paying high $$$ to be held hostage by yet another $240 fill up of urea or your car will be rendered inoperable after 1200 miles and a handful of starts.

Surely technology will render this to the dustbin of bad ideas soon...

Urea is the pure golden syrup filtered out of your bloodstream by your kidneys. It is diluted with excess water, and the mixture is stored in the bladder, to eventually be evacuated through the urethra and into (hopefully) a toilet.

Or, now you can simply relieve yourself into your shiny new Benz, and help save the World!!!

Hooray for tree-huggers!!! They've installed a loo in my truck!!!
