I've been browsing want/for sale ads in Ebay for various car-related paraphenilia, and two models that seem to get messed up a lot are:

Le Sabre (Buick)
Fireflite (De Soto)

which are often seen as:

Le SabER or LA Sabre (or both )
FireFLIGHT

I know there are more, so I thought it would be fun to let everyone release their biggest pet peeves!

Oh, and don't worry about your non-automotive spelling here. All is forgiven!
