Evidently I'm in GM mode today so posting a couple of questions, oop.

I'm GMing for some delightfully creative Smugglers who decided their vehicle is a sparkcraft duck-boat (able to transform and drive on both land and water) named Herbie. I said yes, absolutely, but there's a drawback to having such a versatile vehicle - Herbie is frankenstein'd together with a spark and a prayer, and he breaks easily. The crew has a repeating 4-clock called "Herbie is Broken," which I tick every time the vehicle transforms.

My question is: what cost would you set to repair Herbie once he breaks down? My first thought was spend 1 downtime action and/or 1 coin to get him fixed, or maybe have someone make a Tinker roll during downtime to un-tick the clock (similar to healing), but I'm curious what others would suggest.
