From kids I've only had "RED CAR" from an intellectually challenged pie fan. And "Chitty Chitty BangBang" from another.
At Gaydon few years ago a father & son were looking at my Roadster. The son was about 8. I asked him if he'd like to sit in it. Initially he declined - obviously the message not to get in strangers cars had sunk in. Once his dad had given him the ok he was in. He will never forget that experience and that's how it begins.
My 4/4 has often been accused of being a Bentley by French people (I guess it's the wings on the logo), I've been asked if it's an Aston Martin on a couple of occasions, and yesterday an old lady on the pavement as I crawled by in heavy traffic asked me if it was a Delage (which I felt was rather swish....).
I'm often congratulated on how brilliantly I've restored it, but never been asked if it's a kit car. They don't really have such things over here as the whole business of "conformité" makes it extremely difficult.
