I presently own a MT car but if I ever purchase a G35, it will be an AT cause I'm getting really sick of MT. I've been driving that car for more then 6 years and eventhough I'm still having fun, sometime, it can really be a pain in the a**. I don't have a problem with trafic for a reason or another, it seems to be more on open road. In my MT, I just feel like racing all the time (which is not a good thing as trafic ticket can pile up fast) but when I drive my brother's Lexus IS300 AT, it just feel more relax. I think I'm simply outgroing the boy racer that was once in me .
