LOL.
I can SO relate. My wife and I are both doctors (General Practitioners) in a small (10,000 population) town, inhabited mostly by farmers and pretty reserved people. It's a great place to live, but it isn't infrequently, that a person will "joke" that we are being paid too much, when I pull in with my M3, she pulls in right beside me with her M Roadster, and soon, with her X6M.....
We are a VERY quiet couple - apart from our cars, we actually go out of our way to downplay our incomes.
It actually sucks having a guilt complex about driving what you do. We don't have kids - don't drink or smoke, so we did up our house in a pretty lavish manner (again, INSIDE - from the outside, it looks pretty mainstream), and we drive nice cars.
More and more, I am following the adage - "you only go around once".
However, others' perception of you can be a little wearing.
Maybe I'll just buy something small and domestic, to avoid it all......

- who am I kidding - No way, man. when I was in Ireland, I loved the phrase "F*** the begrudgers"........... too true.
