Back on topic, I wouldn't be surprised to see Honda come in for the sponsorship, should GM leave the pavillion.
The switch from GM to Honda worked great for Disneyland several years ago, and Honda has proved to be a good partner for Disneyland events.
Honda has also proved to be a good partner for America, building factories and assembly lines in America, while GM sends them to foreign countries staffed by foreign workers building their "American" cars on foreign soil.
The Chevrolet Impala, 2010 Camaro, Equinox, Silverado, Sierra, and the Buick Lacrosse and Allure are all
built in Canada by foreign workers on foreign soil. The Chevrolet Avalanche, HHR, and Suburban, the GMC Yukon, and the Cadillac Escalade ESV and EXT are all
built in Mexico by foreign workers on foreign soil. The Pontiac G8 sedan and upcoming G8 sport truck is
built in Australia and then shipped acrosss the ocean to be sold here in this country as an "American" car. Same thing with the Chevrolet Aveo that is
built in South Korea and shipped across the ocean, or the Saturn Astra that is
built in Belgium and shipped across the ocean.
The myth of a 21st century "American" car is pure folly. And try telling that to the good and honest Ohioans who build the Accords from the tires up, or the good and honest Californians who build Toyota Corolla's and Tacomas, or the Texans who build Toyota Tundras, or the Alabamans who build all those Hyundais, or the South Carolinians who build all those BMW's, etc., etc.
General Motors doesn't deserve one penny of my tax money for the past 30 YEARS of their poor management and lowered expectations wrapped in an American flag.
SHAME ON DETROIT for flying in to DC in their corporate jets with their hands out!
Disney could, and should, find a much more suitable sponsor for the aging Test Track attraction. The pavilion overall needs an update, and I would think Honda would be a good place to start. Honda seems to really like being at Disneyland, and I bet they'd be open to considering moving in to WDW as well.
