Simple setup where people will drive their car into the garage and your employees diagnose the car and have a small repair animation anywhere on the car. be a great business opportunity to expand into the automotive side of things as well repairing your own car for free at your own shop. maybe including a shop in the front where we can sell oil and some automotive parts like tires, etc…
If you took it really far maybe even doing upgrades on your personal car.
Can also be simple like adding auto park feature to any vehicle, better fuel mileage, changing the color of the car we bought, more durability, upgrading the engine, etc.
