I am intrigued by the X3 M40i. I didn't know about its existence before I bought my X5. If I had to be honest, I prefer the overall exterior look of the X3, but the X5's interior is way better. Wish I had at least driven the X3 M40i
I went to the online configurator and saw that a fully optioned X3 M40i was still less than the sticker of my moderately equipped X5
