my dealor has always been great - boxster, once they gave me a Cayenne GTS for a week when my 996 had the RMS failure. got a pano turbo and a 911 turbo for a weekend but i have been buying there for 5 years and some good referrals but anyway, as said they have always been good.

 

I got a Panamera 4 loaner (3.6L).
Underpowered and a sadly forgettable drive - Not sure why anyone would purchase this build.

 

My dealer gave me a 2013 Audi A7 as a loaner while they were doing warranty work on my '12 Cayenne S. The A7 is a nice car and it's been fun to drive a different brand!
