The main difference is the big fat fender / wheel arches. They're gone. So is the side moulding between them.
This is a huge difference.
The leading edge of the rear fender and the trailing edge of the front fender went on a serious diet.
That means a cleaner, lighter more refined side view.
The car previously looked awesome from the front, rear and any 3/4 views. But the side view was a disaster.
Aside from this all new side view there's an all new rear face with new tail lights, new side scoops, new front hood scoops, a new dash and electronics, a revised suspension all around and awesome new wheels. Other parts on the Journey page show bits of these improvements.
