Hey Brian,
I'm glad you liked the ES. I was pretty sure that once you drove one you would find out for yourself that it is a true luxury car,Well beyond the Buick. I have the premium sound system in my 2013 ES and I really enjoy it. I did however make one modification to fill out the bottom notes that to my ears, were weak. I put an additional amplifier and small suwoofer (8") in the trunk. To my hearing that really made a differance. I would love to have the Mark Levinson system but I also like to keep the $2,500. in my pocket.
Let us know when you make your purchase/lease and post some pics of your new baby!
Paul
