i dunno, depends on the girl..
i have a subaru wrx sti, lots of money, steady job in the military and im still single..mostly by choice, got out of a 1 year ltr in march but rite now i am happy just doing my own thing..
obviously these things play a large role but they arent everything.. just be working towards them if u dont already have them..
owen
ps - big **** definitely wont hurt ur chances either
