Dollar - Mustang @ Dollar LAX

I just want to find out if the mustang comes with a premium or just a basic sound system? Thanks

I have seen some Mustangs with the Shaker system in it, but most of them are the regular ones. The ones that do have the Shaker system are the ones that have the door sill lighting and/or lighting in the foot area. Plus, its at LAX so I doubt they won't have some cars with upgraded systems/trim levels

and its a CHOICE location so you can look around and see which mustang you want.
