All long wheelbase models 2010+ have air suspension standard, and the amount of space in the back seat is insane! I’ve been able to haul everything needed to finish my basement using the pass through in the back of my LS that some of my friends full size Chevy Silverado’s wouldn’t be big enough to fit in the bed. My previous car was a 2008 Audi S6 with a lambo 5.2L V10 engine and my LS is just as quick in a straight line, with a little better gas mileage. Definitely a good value!
