I really think you should test drive the 2.5L Cx5 and the 28i X1 for an apples to apples comparison. If you're within 8k for a 35i the 28i MSRP comes in at $6000 less, so you are looking at a $2000 difference between the Cx5 and 28i X1. 50+ HP/Torque is a pretty significant upgrade, even if it isn't the full 300HP.
