If it helps, I've found a good thing to say is a range of how much they're worth, sometimes adding 'and I paid less than that'.
Every time I was approached (gas station, etc) and didn't feel like getting in a discussion, I would respond I was a detailer taking the car to/from customer. That would leave me alone with no animosity or curiousness.
And back when that song was written, I dare say there was no Maserati on the planet that would have done 185, unless dropped nose first from 25,000 feet... But hey. It rhymed.
A good friend of mine, that is of Chinese ancestry, told me that when approached about his car(s) (he had a few nice exotics), and didn't feel like talking, he would just pretend that he didn't speak English...LOL!
Just had a guy ask me if I was famous. I asked him if he knew who I was and he said no. I replied, "well I guess I'm not famous".
Most of the time, I am more than happy to answer a few questions or talk about my car. Only a few people have been annoying; I have been asked if it's a Mustang, a Karman-Ghia, (!) and whether it's a Dino or a Boxer (as if all Ferraris are one or the other. ) Most annoying are the guys who proclaim to know more about the car than I do, usually with wildly inaccurate "facts," then proceed to tell me what they are. I've only encountered one really rude guy, who yelled at me in traffic while I had my windows down, "Hey, Ferrari! F*** you!" I responded with, "Thanks! I like it, too!"
What would be awesome if you looked at them and in a straight face and totally normally just said "I don't speak English, I'm sorry." And keep repeating that with whatever they reply. Again, in a normal manner and with a straight face.
In my area I have received a lot of positive comments. Keep in mind that a jacked up 4x4 is the exotic vehicle of choice where I live so when I first got my car, I was expecting their to be some snide comments. One afternoon I was driving over to my friends house and as a person who was riding a motorcycle was coming toward me (in the opposite lane), apparently didn't like my car, so he decided to flip me off as he went by. Not sure what prompted his reaction as I was behind a car and there was another car behind me.
Eek! Where in Michigan are you from? Ferrari are very rare in my corner of the Metroplex, but I've gotten nothing but positive response in my time of F-car ownership. T
That's funny. Hopefully I'll never find myself in a position where this would seem like the only out, but I hope I remember it if that happens. Unfortunately, driving *any* exotic seems to bring out the worst in a certain segment of the populace.
