IMO, if you want a convertible sports car, and you need room for four, the BMW M3 is the only car to get. The E36(older) , E46(newer), and E92(newest) bodystyles have all been fantastic sports cars with room for four. The M3 will not handle the same as a boxster, thats a given due to different dynamics, i.e. engine location, size, and weight. But, the M3 is similar in that you get a lot of performance in a stock package. Their power to weight ratios always seem ideal as well. I believe an M3 would put a smile on your face everytime you drive it, like a boxster would, just probably not quite as big.
