I thought you could go to a dealership and have them type in the VIN and check the carfax free of charge.

Aero package would include a rear spoiler.
Sports package includes 19" Rays Wheels and suspension (also includes some underbody air panel crap bs)

 

i will call a buddy to run my vin. didnt think of callin the dealer seein as they gotta run all the trade ins.

u can get the aero package with out the spoiler. now if i read this correct u cant get teh aero package with out the sports package(19s and sport suspensin, orange stitching on steering wheel and sport pedals) but u can get the sport package with out the aero kit. either way u have a choose of the spoiler or non spoiler.

now if u have the performance tire and wheelpackage that includes 18s it excludes everything else
