Just enough truth among the nonsense to be scary for most people. Actually, the "truth" is mostly due to ambiguities in his statements. Ex:
...If they are not [a Master Upfitter] - be aware that Mercedes can decline any warranty work as a result of unapproved modifications made to their products.
This statement is either true or false, depending on how you interpret "any warranty work as a result"
If he means literally "any warranty work", it is nonsense.
If he means "any warranty work for a failure provably caused by
an unapproved modification" then the statement is correct.
BUT, as I said above, as far as I know, being a Master Upfitter has nothing to do with your warranty. I believe that damage caused by an approved modification would be covered whether the upifitter is a Master Upfitter or not. Most of the rules are laid out in the Bodybuilder's Guide, which anyone can download. I suppose, though, that only MU members are able to apply for waivers or get rulings on things not covered in the Guide.
