It depends on your taste to see the cars, motorcycles and descriptions of the same, there are also cars - which came out in TV series, movies, very old, - and the cars that are in the museum are F1, monsters, modified cars. Your time as about 2 to 2.5 hours. You will not regret.
Google maps information says that the average person spends 2 1/2 hours there, but I was there a week before for the first time and spent six hours. but I like to take my time and read the statements about the exhibits.

About 1.5 hours
Give yourself two hours for the regular museum. But go to the Vault for 90 or 120 minutes to get the best the museum has to offer.
