 I bought my 2003 infiniti g35 2 and a half years ago with about 150,000 miles. It was pretty cheep and still in good shape when i bought it. However after putting almost 30,000 miles on it things have gone wrong. For one i have an exhaust leak and the piping is rusted out. I had low profile tires which i had to get new ones. A couple weeks ago i brought it to my shop to get ball joints and wheel barrings on it because of a real bad "clanking" noise. Now it needs brakes(probably because all of the new parts i put in it) however I love this sporty looking car, and dreading the day i have to sell it. I love the ride and its very comfterable all the way around. Another slight problem ive had with this car is the passanger side seat is stuck foward, my trunk will not open and my lock and unlock part of the key doesnt work(maybe because i dropped it to many times).
