I am interested in buying a 2004 Infiniti 135, is it a good vheicle to get?

I have been looking around for something that is a good buy, i am not planing on paying $300 or more on monthly payments. i was looking at the 2003 Nissan Max, but about two years ago my uncle brought a 2002 Infiniti I30 so i thought to myself why not get a Infiniti I35 the body shape is the about the same as the 2003 Nissan Max although nissan said that buy 2004 they changed the number from I30 to I35 but to me it just seem that the I35 has a little sportier look than the I30, now when my uncle brought the car it had 78,000 miles on it, he told me now it has 132,000 miles on it and he had to do is replace one of the head light and he just had to put in a new transmission, other than that his car has worked out fine, one of the days whiles he was out on a business trip my aunt allowed me to drive his car around town, now they live in Philadelphia and there were certain streets that have pot holes etc, whiles driving his car even over the pot holes i could not feel anything, the only thing i don`t like about this car is the fact that it has a stiff feeling to it whiles driving it, all of that being said is the 2004 Infiniti I35 a decent vheicle to get?
