Trademarks are adjectives, not nouns. When you apply for a trademark, your lawyer will insist that you provide samples of marketing materials which use the mark as an adjective. So Toyota probably occasionally refers to "Toyota Automobiles", and I'd bet that Daimler's marketing refers to "Smart(tm) cars" all over the place... and they do, see google results for ["smart cars" site:smart.com] Looking at the Google results for [smart cars] and ["smartcars"], it boggles the mind that anyone would try to register a new mark in the auto sector like that. So much potential confusion!
