I went to look at the CLA AMG before the RS3 and the sales guy was a ass to me (not wanting me to order a new one but having one in stock) plus the dash looks like someone has gone to halfards and stuck a screen on the dash. Also its not the 5 pot I've got now! That was a big thing for me.
If the sales guy would let me pick the car and have it built i don't think i would of looked at the RS3 buy VERY glad i did. Didn't even know about RS3 till i went to Audi and thought this is way better then the merc!
