You should all move to England!
That great British reserve means people you don't know generally won't just walk up to you and start talking.
The ones who do have had to pluck-up a huge amount of courage to come over and ask about the car - and (so far) they are ALWAYS genuinely interested in the car, what it is and, of course, how much fuel it uses!
(A US gallon of 97ron here is about $10 right now.)
The largest group are my age (say, 40 to 55) and we have all grown-up fascinated by the cars we saw on TV in all those 70s cop shows and, naturally, DoH (Unfortunate acronym, but hey..)
Although stopping for petrol takes longer sometimes, it is always nice to chat to people who like the car - except last week when I had just sprayed the rear panel with a pint of ESSO!
Best wishes to all.
