Just got a CPO 2008 IS 250. Only has 17,150 miles. How do I tell what packages were purchased with this car.

I have: Navigation, 18" wheels, heated/cooled seats


I don't have: Memory seats, tilting mirrors when in reverse, no
Mark Levinson sound that I can tell, which I did have in my LS 430.

Seems like a strange combination. Navigation without Mark Levinson sound? Heated/Cooled seats but
no tilting mirrors? Can you tell me what package this could be. How do I tell if I have sports package?
I don't have aluminum pedals but do have staggered front/back 18" wheels.

Could the options that the car has been purchased individually at time of sale?

Also, rear speakers are really weak compared to front speakers. Is this typical or should I have dealer check to see that all speakers are working?

Thanks for your help.

Cheers
