Luxury cars are generally the best place to turn when you're looking to get your hands on the latest in in-car technology. Case in point: Lexus' $58,950 ($68,007 as tested) GS450h. This hybrid luxury sedan features a ginormous 12.5-inch display, multiple drive modes and smartphone connectivity, complete with its own app suite. We haven't seen a car packed with this much technology since the last Transformers movie. So is the GS the best teched-out luxury sedan money can buy? Check it out.
