On Location Achievement
Take a photo of any car in every Home Space.
From the career screen, select Cars > Change Homespace, and make sure you are on the first one. Take a picture of your car (it doesn't have to get uploaded, only saved locally) and switch home-spaces to the next one in the queue... wash, rinse, and repeat. There are six home-spaces which should take less than 5 minutes to snap a photograph.
