1) I like the looks of the IS300
Your opinion, can't really argue that one. But it still looks rice to me
2) The 3-Series already looks old to me
Just don't get this one? The new 3-series is only 3 years old.
3) Lexus/Toyota quality (I have a '95 Camry now and it is still rock solid)
My 95 325i is rock solid. BMW quality does not match Toyota's but it's not as far behind as you think
4) BMW's aren't known for their quality/customer service. They're nice to you up until you buy it...then they treat you like sh!t.
Well my solution: After the warranty is over, find a good mechanic. Mine does a wonderful job and has pretty good customer service
5) The 5-speed will make the IS300 a much better car
Speculation? I agree that it will be a better car, but much better?
6) The 3-Series is overrated and they overboosted the steering which many seem to be complaining about
overrated? how? Yes the steering is overboosted, but it's still better than that of the Lexus. My grades for steering:
My 95 325i: Almost Perfect
2001 325i: Very Good
2000 IS300: Pretty good
