The IS300 was not without problems. If you look at IS300.net's forum, you'll see what kind of problems they bitched about. When I was looking at the E46 vs. IS300, I thought that the savings wasn't going to be worth it. Why? The IS300 also had it's share of problems. Also, with the car not being nearly as exciting as the BMW, well...what the heck is the point. I would have been buying a car that wouldn't have been as satisfying, AND it would have had it's own annoying and well-known (among IS300 owners) problems. So, I figured forget the IS300. Will the IS350 be different?
I don't really care. I can't imagine that when I sit behind the wheel that I'll find it to be as satisfying as a BMW.
