A lot of the Hertz LaCrosses also have the driver confidence package, which adds active hid lights, blind spot indicators, and heads up display.
I've at least twice received touring level LaCrosses from Hertz, and after driving one of these purely luxurious vehicles every future premium car rental will be thoroughly disappointing for you!
(At 27, add me to the list of kids that doesn't want to wait for retirement to buy a Buick thanks to this car!)
