man, i know i'm gonna get flammed to hell but here is my only expecience with a nissan:
about 4 years ago i wanted to get a new car so i went and test drove a few. went to the nissan dealership one night and test drove an altima, manual transmission. man, it started badly. the dealer didn't know how to drive manual so after a couple of failed attempts by him, he finally let me drive it out of the parking lot. and then... that was the worst manual transmission i have EVER driven. it didn't get into gear well, sluggish, etc... just an all around piece of sh1t.
i've read that the new models are pretty good as far as engine now, but that one experience with a piece of sh1t car just turned me off completly forever. that and me dusting my friends nissan v6 in my old gti in a little race.
