Yes, but I don't have one, that's why I'm asking if you have a saved game.if you have a save during or before brenda quest just redo it then and for the shop part you just have to wait for a lady to go in front of the register then you can proceed outside. Once there you take the red car in the parking lot (scene) and bring back brenda back to her house and the car to the another house on the left i think
