"Hard to fit the car in a two-car garage next to another car and still to be able to open the doors, though."

Absolutely false:

the doors of a DeLorean or for that matter any other gull-wing doors pivoting near the center of the car, swing upward, not outward as they open.

That, in fact, is the whole point of having gull-wing doors - the fact that very little clearance is required to an adjacent vehicle.

Agreed, they probably require less sideways space than a conventional door.
