+1. Rented one for 3-4 days a few years ago and loved it.we'll probably pick up a beater car in the coming year (wife promised that M3 is ok in 2-3 years, need a better parking situation first), and I'd totally consider a 500. The problem is whenever we travel to visit relatives, it's always a car packed with 3 people, 2 dogs (one of them very big), and all of the luggage. Couldn't swing all that in the 500 for the 4-5 hour drive.
