For those that need to see an M3 Convertible on American soil to believe it really exists, BMW just unveiled it in New York. The 414bhp, V8 supercar will set you back $65,700, a hefty $11,000 premium over the sedan and $8,000 more than the coupe. That extra chunk of change will get you a folding hardtop, the wind in your hair and a higher weight. The sedan and coupe will be available in dealers next week, the convertible later this year. Let's hope none of you are silly enough to pay $100,000 for one.
