Leasing vehicle to another party: What am I leaving out?

thread title misspelling:  **Another party**

I'll try to make this brief, but I am trying to make sure I have all of our bases covered, hence why I started the thread.

I am one of 3 trustees at my church.  We have a van that we have for picking people up for services.  Currently, we are not using the van for any pickups.  A friend at work asked about keeping an eye for him (the church) for a van because they are needing something for picking up some new members for services.  

I (and the other trustees) hate to see the van sitting idle and would rather it be used by someone for something useful, so we have tossed around the idea of "leasing" the vehicle to them until a: we need it back, b: they buy their own, or c: (unlikely) they are not taking care of it.  The lease value would be something small (like a dollar...) but would require them to hold insurance for the vehicle and occupants.  The would most likely take care of servicing, but realistically, they aren't going to be driving enough to need to do any regular maintenance.  

A simple contract that lists our church as Lessor to their church as lessee and requires proper insurance, inspections, and upkeep...what am I missing?  

I've been involved with two different churches and three buses.  

Sell it to them.  They are a money pit. 

Yeah, I'd sell it to them cheaply before doing a lease. Too many possible downsides to leasing it out. You can always buy another van if the need arises. Or if needed for a couple outings a year, just rent one for those couple times a year.

In the early 1980's on a high school student event my 20 year old friend was the driver and the 1965 Bluebird, well used ex-school bus broke down.

He had to walk to a farmhouse and ask for water as the bus had overheated on a cold winter day.  The lady gave him the look like a scam was being pulled......
