Ok, I just got to 10. I started this thread simply because I wondered if the cars only go to Tier 5, then what's the point beyond that.
One thing I have noticed so far is that if I choose cash instead of a car or suit, the car and suit will come up later as choices, but if I choose the car, it doesn't look to repeat. I can't remember choosing the suit, so I don't know if it'll throw a "repeat" at you.
