My husband and I had our first visit to this museum today and were surprised that they were also having a special event..Swedish Car Days on the Lawn. So we strolled around the lawn and saw Volvos and Saabs, both old and new. We then went in the museum which grew out of the tradition of the Anderson's (socialites at the turn of the century) opening up their carriage house to share their collection of cars with others. The museum is on two floors and had a collection of antique and modern cars along with some fashion items to complement the car in some cases. There were even some antique electric cars. My husband is a car nut, so I will take his opinion that it was a good collection and he recommended a very good rating. I did notice a gift ship, restrooms,and a small "cafe". I also noticed a playroom for kids on the bottom floor, which may come in handy for families with small children. I did not look for an elevator..so sorry I cannot speak to that. However, I think there is access to the outside from both floors because the museum is on a hill. It should also be noted that the setting is pretty and the museum is very close to the Arnold Arboretum. We visited both on the same day.
