154000 vs 74,000 miles. I would keep yours. Chicago? I would keep it just for bad weather days! Mine was going to be a temporary vehicle while doing timing chains on a GMC 3.6 Acadia. Now, the Acadia has been passed on my folks. The X5 will be wifey's daily driver. She has a heavy foot compared to mine.

Can't beat dependability! Keep it!
