He got the "electric roof" version, which had this awful hodgepodge for pneumatic rams, high pressure air hoses and couplings, and a seriously underpowered hydraulic pump - with instructions to fill the system with auto transmission fluid.
It was _not_ a well designed and reliable system, and some of the failure modes left the roof/door clamped down. He kept a pocket knife in th4e glovebox so you could stab the hoses to release the hydraulic fluid and manually push the roof open.
It wasn't until it failed closed while he was taking his girlfriend to the high school formal/dance, then ruined her dress by getting red auto trans fluid on it that he bit the bullet and threw all the supplied parts away and replaced it all with electric liner actuators...
For those who haven't clicked the link: The roof/doors are all one big assembly that hinges up and away, like Lambo doors for the entire top of the car.
Here's a video describing how to use the manual overrides (none are in plain sight)... https://www.youtube.com/watch?v=DLDqmGQU6L0
