Ah no, there are four then and they aren't mutually exclusive:
 * All Cars
 * All Events
 * All Upgrades
 * All Customisations

You can't do 2 without 1 as every car is in at least 1 event, you also can't do 3 without 1 because the in game upgrade counter counts all upgrades even if you don't own the car. The information comes from your profile page (hence why people are required to post them as proof). The right image below shows that I had all cars (179/179) but not all upgrades (maximum upgrades is currently 4788). The left image shows I had all events (100% completion).

The last category is the one that Michael hasn't completed and it is pure laziness on his part ;-). Customisations are free once you are fully upgraded but they add to your garage value (see right image). Current maximum garage value is 1,017,334,495.

The only thing you can't find out in game is the current maximum number of upgrades and the maximum garage value. You need to reach these levels to know that these values are.
