Throttle house did a review on the 1le vs an RS3 and M2 Comp. here...
Very good review before driving the camaro I took their word for it. I never drove an M2 competition but they say it's better. I have never driven an M2 comp but I own a 1M and the camaro 1le beats that for me atleast. I can't imagine an m2 is better than a 1M or an e92 m3 but I could be mistaken!
