Thanks, TA2001. Didnt ask them for a loaner due to having the E55 as my daily driver. When I bring her in for the short shifter and exhaust, I will let you know what they give me for a loaner. When I had my Cayenne, the first time, they gave me a Ford Escape, nothing against the vehicle, it just didnt seem "like" as a loaner. Subsequent visits and expressing my opinion on a "like" vehicle, they gave me a BMW325, Cayenne S, and a Jag XJ8 for other visits. Pretty nice loaner cars
Sounds like you scored with the Z4 demo for the day!
