I just test drove the EX and SX Koup yesterday and I really liked them both. However I did not notice a huge difference in performance. I think I am going to get the EX Koup but I really like the rims that come on the SX. Do you think the dealer will give me the option to put the 17" rims from the SX model on a EX lease if I ask for them? Thank you for your help.
