I think that service in the US is Fantastic!
In France, if you need to bring your Brand New X5 for a warranty repair, BMW no longer lend you a Car.

My PDC button and steering wheel memory system was not working from day 1.
I already left my car one day to my Dealer and now they are asking me to bring it back for another 2 to 3 days for reprogramming and part change. Of course, they want me to use the public transportation! I did it for the first day and it sucks!

I called the BMW customer support, who confirmed that BMW only give a courtesy car if you have a total break down.
I did it in the past for another car and I got a nice tiny Fiat from a rental company.

I bought a 7 , 5 and an X5 in the last 5 years. The X5 is a $130k car (90Euros) .
I am furious!

I strongly advise the European customer to negotiate the loan of a car when they place an order.
