I did a search for a spotted thread for Louisiana but I couldn't find one so I thought I'd fire one up.
I saw a silver 370 today in Baton Rouge on Siegen Lane near I-10 with a really nice sounding exhaust on it. It was really low. Probably on coilovers. He was sporting a The370z.com sticker so I'm assuming he comes around from time to time?
Anywho, whoever you are, your Z sounded excellent!
