The automobile body is a total environment. An evaluation of this environment should include consideration of: seats, vision, noise level, heating system, ease of entry, ease of maintenance, instrumentation, trunk space, exterior, and styling. These points and others are reported in an annual survey made by Popular Mechanics magazine. The owners' report is sent to drivers all over the country who evaluate their new cars on the basis of likes and dislikes. The tabulated results can be a guide of the engineer and stylist alike.
