I'm torn. I think it isnt in the greatest of taste, but am facinated by statistics and demographics.
Income of course doesnt say too much about affordability. I make a pretty decent living but am certainly not rich. I paid for my used exige with cash as I am mostly frugal and cost of living in texas is low. Now I have a wife and child my money goes alot faster!
My sister and husband have a combined income well off your chart, yet they struggle alot more than me. They live in NYC and have huge daycare fees. Their cars are financed.
When I bought the elise in 2007, I made significantly less than I do now. Maybe even low enough for it to be considered a poor choice. However, I made a deal with myself that if the car was written off or required huge maintenance (igonorant to lotus at the time), I would chalk it up as a life lesson and move on. It was paid for and had another car.
Anyways too many variables are between income and affordability.
Seriously, my car is small
