NOT a Nova...

Considering the Duster was a direct attempt to steal Nive sale and to the untrained eye (or moron Chevy wanna be car guy) they look the same. I can stretch the “They look similar” to some people since it was made to compete with the Nova.

If some (Moron) guy comes up close to it and starts with the “Nice Nova” comment, I ask where he went to school, the whole you look familiar thing and such….
I normally say something like, “You remind me of a dude that got kicked out of school from the special education classes. Did you have read compression problems in school?”

What ever there reply is, I walk them to the car and politely say, the manufacturer’s badging is here and the car model name is here and the obvious differences are this and that while smiling and pointing.

Kill’em with kindness and with a side dish of ridicule on a polite level. If there slightly arrogant, I’ll end the conversation with,
“Now you’ve been properly schooled. No worries.”
