yah, lambo's have wow factor thats for sure in my area. i kinda prefer the ferrari's though...i like their sound better.
anyway i would look out of place if i owned one. each time i take one out it will look like some wannabie korean guy in a birthday rental.
... or better yet, maybe people will think 'ahh, asian restaurant owner, follow him to his wok n wok or tempura place, it must be good!' i would then have a caravan of buick regals and ford fusion rednecks following me. wtf...
just be happy you have a Z and a healthy body to go with it. you dont need huge bucks to be happy.
