Classic car/truck project restoration theme.

Game would need to have some timer elements included so if you didn’t score enough points fast enough, your rebuild project would drop in status from “project” to lawn ornament to rust heap to second mortgage on the house to neighbor sold it for scrap metal.

But the bonuses would include things like upgrades to crate motor, manual 5-speed, custom paint job, Retro seat coverings and the like.
A special layer of the playfield would be created to “ramp into” once you’ve built your vehicle of choice up with competitive feedback like “you won best of show”, “swap for a ‘69 Camaro”, or “broke down before you arrived at the event” type quotes.

I’d sell my wife’s minivan to buy one of these that was well done.
Then again, I’d sell her minivan to buy a sweet ‘56 F100!
