You would be sorely disappointed if you drove to Chicago...they have moved their facilities to Houston, TX.
The best way to get something going is to e-mail the guys at Eurocharged through their website (
Eurocharged Performance and Tuning- Exotic and European Tuning Specialists) and ask them....they are usually pretty good about getting things rolling between all of the MB/BMW/Audi crowd. If they can get enough interest, Jerry will surely make a trip up this way.
FYI, Baltimore seems to be the general area they head to for NE tuning days as it is a bit more centralized and can hit people from NY all the way down to NC if they are willing to make the drive.
