For example, compare the BMW 5 series ($47,795) and BMW 7 Series ($71,895). Clearly, with the 7 Series, BMW buyers are getting a slightly larger sedan. An updated version of the car is rolling into showrooms this summer, but to quote one dealer, "The 5 series is so nice it made it very easy for the returning 7 series customer to downsize without a lot of compromise."That ultimately may be what the slowdown in luxury cars over $75,000 is all about.
