I am very much in the same boat as merli... in my area Lines arent too common, the chicks seem to like a change from the commodores etc.
My mates usually do most of the talking about my car for me. I just play it down.
But then again my current love interest is a ricer like me and she has a louder stereo and exhaust too...
Which is good i feel that it is more based on the people we are not the cars we drive.
