2007 Lexus GS 450hCredit: $1,550
Status: In the penalty phase with all other Toyotas, and just arriving on dealer lots. Get used to a $778 credit starting in October and a $388 credit in April of 2007.
Pros: It goes really fast and is fun to drive with an exceptionally smooth power delivery. It burns clean as a Super Ultra Low Emissions Vehicle (SULEV), and gets good gas mileage (25/28 mpg rating) for the performance it delivers.
Cons: Cramped interior, and availability: good luck getting one of these ponies, as initial volume is low. As with many of their new vehicles, Lexus/Toyota will start slow and build demand.
