I'm actually one of the original members. We used to be the Chicago chapter of DTMPower.net like 5 or 6 years ago....then we were BMWX.net for maybe 6 months, until a legal squabble with BMWNA....changed to Euroteknik.com maybe 5 years ago and haven't looked back.
We started out as a BMW community and had meets every Thursday night at Fuddruckers in Schaumburg....got bigger and bigger and now include VAG cars as well as Saab/Volvo/Merc/Jag/Porsche/basically anything euro.
I used to be really involved, but drifted away since most of the people that started the group left/moved on, but I still post there.
