Advice on Vehicle Healing

Hey all!
Just started Mc'ing my First Hack!

My question is about Vehicle healing...

I'm looking at the Savyhead workspace as a mechanic for this...each level of harm could be one+ from the list to heal?

Example: 3 harm on vehicle may cost: 3 from the list: 6 hours work, 1+ barter, and you have go and get an ______ from Shit-face's Truck.

Or is that too much cost?

Compared to Pc/Npc healing seems reasonable

Or simply making players spend barter per harm level? (thats not as fun though)

What has worked for you?  

Thanks in advance,

I just use the savvyhead workspace rules as-is, deciding case by case what it'll take. There's no reason to insist that each level of harm means an additional thing.

Awesome, thanks for that Vincent!
