I recently rented an Optima for a week trip. It was by far the most enjoyable car I have ever driven..I recently dumped my Mercedes AMG last month for numerous ongoing problems. The Optima was responsive, comfortable, quick acceleration and the gas mileage exceeded 30 mpg on the highway. I am planning to buy one in the next 30 days. I understand that one week is not the same as owning, but I was that impressed with the car.
