Magic Mountain is a super fun Rollercoaster Park close to LA I loved it and can't wait to go there again. Only problems are long waiting times for the rides, but still worth it. After a half day we decided to leave because the lines got to long. So we went to the Petersen Automotive Museum.
Petersen Museum has new and old cars starting at the first one ever build ending up at the Jaguar C-X75 which was the stunt car in the new James Bond Spectre. I liked the old Porsche Racecars.
