Great question. Here are my current stats. I currently have well over 100 cars. I have purchased 110 cars as of now, but have earned at least 50-75 cars from rewards. Close to 200 total I’d say.

Keep in mind I've got 200 hours of playtime in HT7, yet only 60 hours of actual driving. That means I’ve spent approximately 140 hours designing and photographing my livery designs.
