Spotted '09 silverstone e90 m3 w/19's, going north on Preston Rd. and crossing Park blvd (Plano).
I believe he was an Indian guy. My wife & I were in our SUV and we tried to give him a thumbs up, but he didn't see us unfortunately. Also, he had an M3POST.com sticker on his window.
I'm almost sure it was the member named 'Suprane'. I searched on the 'M3POST sticker thread', and he was the most recent one who posted on the thread. He took some pics also......Which provided proof of his silver e90 m3, and his profile mentioned he was located in Dallas.
