Pay attention to the case after the preposition 'in'. When you describe movement into the garage, you use the accusative ('in die Garage'). When you describe a state or position, you use the dative ('in der Garage').

The verb used helps distinguish the two meanings. Verbs like 'parken' (to park), 'fahren' (to drive), or 'stehen' (to stand/be parked) point to the storage space for a vehicle. Verbs like 'bringen' (to bring/take) or 'reparieren lassen' (to have repaired) point to the auto repair shop.

'der Parkplatz' and 'die Garage' both have to do with parking a car. A 'Parkplatz' is a designated area, often outdoors or on a larger site. A 'Garage' is a room or small building, usually lockable and protected. The words can be confused because you park a car in both places. 'Parkplatz' sounds natural when you mean an available space in front of a supermarket, on the street, or in a yard. 'Garage' fits when the car is in an enclosed room.
