Holy hell, That's kinda funny. I was going to offer to trade you mine for your mustang. I just got it for the wife, but now she is talking about a range rover. If you are interested let me know and I will see how serious she is about getting something new.
About the 528's in general. Hers has been great. Extremely fun to drive, you can just cruise comfortably, or drive it aggressively. It handles both nicely. Gas mileage is great, she drive it mostly city and gets around 22 mpg. I say you cant go wrong.
