I drive to work, all freeway speeds and on the "flat". ONE WAY, BUMPER TO BUMPER. No need to pass. Zero acceleration at this speed, but more than need acceleration in town.Have air conditioning, is adequate with tinted windows to keep comfortable at 100 degrees after 10-15 minutes of cooling. Will not stay cool at idling--needs 1500-200 rpm to cool. Adequately. Added cruise control-- millage increased from 42 mpg to 45.6 mpg at 50-60 mph with this change. Nothing breaks, excellent car but VERY NOISY--have double insulated doors with Dynomat sound insulation, it helped ---now I can tell the noise is coming from the floor-- 95-98 db--OSHA action time for this amount of noise is 15 minutes.
