Well, let's look at the basic facts:
1) the museum is open (it was in January 2025), although its website has not been working for a long time, and of the 2 phones, one does not work, and the other cannot be reached((
2) there is no public transport to this steppe, you can get there by car or taxi, from the center of Abu Dhabi it will cost about 150 dirhams there and 150 back (it is better to immediately arrange with the taxi driver to wait for you there for an hour and a half, they readily agree)
3) the entrance costs 55 dirhams per person, if you pay with a card, you will receive a commission of 5 dirhams per transaction
4) there is no water, food, shops or anything else inside, take everything with you. There are only 2 security guards (one at the entrance and the other checking tickets at the entrance), so I think it's not possible to get through by phone.
5) there are really quite a lot of exhibits, they are logically divided into categories (vintage cars / 1950-1960 / 1970-1980 / 1990-2000), as well as by region (there is a section "American cars", "Japanese cars", "European cars"), a leisurely inspection will take about 1-1.5 hours
6) with children, I recommend it, they are interested in not only seeing the world's largest jeep from the Guinness Book of World Records, but also to see how cars have evolved over time.
If you are not indifferent to cars, then you are definitely here. Information about the quantity, cost of the collection, and the owner is available on the Internet. In fact. Located 60 km from Abu Dhabi, you can only get there by rented car or taxi. In the latter case, the taxi driver must wait for you, there is no other way to leave. There is no air conditioning in the hangar where the cars are parked, but it is tolerable, we were in June when it was +45 outside. There's only one caretaker, guy, you pay 55 AED and go, take off as much as you want. The cars are systematized by country and time, many have info plates, the partitions between the rows of cars are mirrored, so they are visible equally in front and behind. In an hour I managed to take a video of all the cars and consider some unique specimens, I could have wandered in this paradise for two, but there was a contract with the taxi driver..
The museum is an hour's drive from Abu Dhabi. As a lover of vintage cars, and cars in general, it was very interesting for me. After half an hour, the wife began to suffer from the heat (the museum is located right in the desert, around dunes and oil rigs), because the construction of the museum is a huge "tent". In general, it is a great place for amateurs, very interesting and rich in collections, but I recommend going without spouses and children - then you can really immerse yourself and consider.
