Our first trip was to Florida from Connecticut, about 1400 miles. We averaged 20 mpg using 89 octane and speeds set at 72 mph (cruise control) The doors leak air and cause a serious distraction when trying to listen to the radio at low volume. The car handles well and performed well. and the ride was pleasant for the most part. You are unable to roll the rear windows down at highway speeds. They flutter to the point where you think your ear drums are going to explode.
I love the performance of the Hemi engine. Just need to quiet it down a little while idling
When the engine is left to idle, it sounds like an egg beater. The noise level makes it sound like it has a million miles on it. The doors leak air at speeds of over 50 mph. it's quite annoying.
