I've been trying to find an example of a GMC Sprint window sticker for years.
You learn something new every day ... I know, 1994 model Ford Bronco's had a window sticker ...AFAIK, trucks didn't have window stickers; manufacturers weren't required by federal law to post MSRP on trucks.
I don't think you will ever find one for a Sprint or an El Camino.
Car window stickers requirement was passed into law on July 7, 1958. At that time only passenger cars were required to have the stickers. Trucks (El Caminos were classified as trucks) were exempt as I recall.
I recall that window stickers were still not required in 1986 when I bought a new El Camino.
The dealer had posted his own window sticker with a price. SUVs, like Blazers and Suburbans were also exempt.
I'm guessing, it was sometime in the 1990s when trucks and SUVs were required to post MSRP on window stickers.
AFAIK, trucks didn't have window stickers; manufacturers weren't required by federal law to post MSRP on trucks. I don't think you will ever find one for a Sprint or an El Camino.
I bet Bob Inhoff (RobinLS5) could verify one way or another. He bought his '70 Elky new and should be able to recall if it came with a window sticker or not. And Bob, if it did come with a window sticker, I would be curious to know which window it was placed in.
