From one newbie to another, there is a shop in Skokie called BodyWerks, not sure how far that is from where you are:dontknow: but they did a real nice match and install on a body kit for my friends Neon.
There's a shop in Crestwood around 135th and Cicero called George's Automotive. Although that's the south suburbs, probably a good 45 minutes from you so that may be too far from you. They do body work and paint jobs. They did a complete overhaul (dent removal, shaved locks, complete paint job) on my old Civic and painted the wing for my RSX so I can definitely vouch for their work. If you call there, ask for Randy and tell him you got their name from Mike in Lombard.
