You may or may not have heard this bit of information, but here it is anyway … as recently as 10 years ago, the one car most likely to be the primary car of a U.S. millionaire (a person with a seven digit net worth excluding primary residence), was … Ford F-150.
The market has shifted towards imports a lot since then, and gasoline is about 3 times more expensive today than it was 10 years ago, so F-150 may have lost some of its appeal. I don’t have any recent figures, but I believe that Honda Civic and Toyota Camry are very popular. If Civic is too small, take a look at Lexus ES300.
