Yeah, it's all about your method of approach... I've seen people pick up chicks in a SEVERELY weathered Mazda sedan... But looks-wise, all you need is a good coat of Meguair's NXT, shine up everything and thoroughly clean the interior since most girls only care about how well you take care of the car, but again, it's mostly attitude since I see hot chicks with ugly dudes all the time.
Besides, I even had one chick that even danced in front of my car while I was waiting for the club to open (which I eventually even danced with her once I got in

), and another chick who randomly blew a kiss at me when I looked over... Too bad she was making a right against a red and I was stuck, 'cuz she was HOT.
