Badge Nazi

Someone who thinks only German cars are good and hates on cars made by companies of other countries. They judge a car based off the car badge/emblem brand and assume any car badge of any non-German company is bad. They overlook the car itself and only care about the German brand name. Hence the term Nazi because they only like German cars and hate every car that isn't from a German brand.

Person: Ooh look at that Corvette!
Badge Nazi: Who cares, any 4-series is better than that because it ain't from the autobahn.
