Sorry about the 2.5 lol but chances are with 100k any engine work that needed to be done was done.
My dad has an 02 Altima 3.5, and he gets very noticeable 1-2 and 2-3 upshift flare from the auto tranny, which was a common problem too.
I'm going to be looking around 70k and then go from there
I'm open to the 3.5, but the 2.5 is still my first choice because of the gas mileage.
