For me it was the combination of a new baby, a business that allowed me to write of the lease expenses, and the aging Prelude SH that gave me 8 good years of stick shift fun.
Never regretted the move, as others have said, you only live once... BUT, I would certainly prioritize the house before the X5. 30 year loan at 3.5%? You will never see that again!
