I received one of the first Lexus GS 450h hybrid sedans. I had been driving an LS model. The GS definitely feels like a step down in luxury. I have been getting a disappointing 20-21 miles per gallon. The interior feels cramped compared to the LS. However, the GS hybrid has plenty of power and is fun to drive. I would think twice before spending the extra money to get the hybrid model of this car.

Trunk space is non-existent. Mileage is disappointing.
