hey guys, new to the forum, this is my first post. I am debating which car I should get. an 08 m3 conv. or an 09 coupe. my main issues are the idrive and the dct.... should I overlooking getting the dct and settling on the older idrive for about 15k off msrp? or should I get the 09 with dct and newer idrive?
