What about all the people receiving calls for old cars? Or those people who don't even have a car? Where are the scammers getting their numbers? Robo-diallers are more likely to be the culprit than a dealership.
Just called my cell, but didn't leave a message.
People ask how they get your number.... take a look at www.truepeoplesearch.com.
When I checked my name, I found addresses and phone numbers that went back years.
