Just spotted: a mobile car service that 'green' tunes your car. Check it out at http://springwise.com/weekly/2010-08-04.htm#greengarage

They do make some improvements over the standard garage treatment - using lead free wheel weights, for example. But does that qualify them as green? Or will that kind of positioning just lead to frustrated consumers throwing the 'greenwash' monkey wrench at them?

Love to hear your thoughts...
