My dad had an Oldsmobile that had metal lettering installed on the trunk lid from the dealer, Something like "SamSmith Buick - Oldsmobile"
So I thought my dad drove a "Buick Oldsmobile" for the longest time. After all, the metal plate was designed to resemble a car logo.
Ironically, when I grew up I once owned an Oldsmobile that developed that problem with the ignition way inside the steering column, so I got another column from a wrecking yard... Out of a Buick.
