If you're planning on reading everything about every car there. It would take over half if the day. If you're anything like me. You browse past most, and read only about the exhibits and cars you like. All I'd say a good 2 hours and 45 min for the vault tour which costs a bit more, but I would definitely do it!
3 hours is a good estimate. When I did the Vault tour it was over 90 minutes.
A WONDERFULL MUSEUM TO VISIT ON MANY OCCASIONS! EXHIBITS KEEP CHANGING. ENJOY.
Normal visit about 1.5 to 2 hours. If you want to see the vault too, add at least 2 more hours. It's worth it if you love cars
3hr. The Vault tour can be hit or miss in terms of the guide's knowledge, but you'll see things that just won't be available otherwise.
I'd plan for at least a couple of hours. If you really like cars, it'll take longer.
