Don’t get stuck on being unique. It’s more important to get started than to get caught on differentiating yourself. Differentiate as you go.
I also wouldn’t get too focused on the wrapping yet. Car detailing is a great idea to get started. Start that TOMORROW and then reassess in 6 months. With some experience and customers it will be much more clear what the best next step is.
There’s a LOT between wanting to do nothing and “being a slave till 70”
