People donating things aren't generally looking for a good deal.
I don't really care about the religious aspect, but if you're calling yourself kars4kids, the proceeds really should go to kids. In general, charities should have to be more up front about how their donations are being used. With rules being stricter as they get bigger. That is to say, the local fire department doesn't need to tell me how much of the hoagie sale is going to beer, but once you're buying commercials there should be some transparency.
As far as car donation options the purple heart is still around. I think at one point either the EFF or the FSF used to do it too, but I can't find it anywhere. Does anyone remember that?
Tons of car donation options exist (I just linked https://www.catholiccharitiesusa.org/ways-to-give/donate-a-v... elsewhere) - but the big IRS loophole was closed (before the charity could just give you a bullshit receipt for the "value" of the car, anything remotely justifiable, now they have to either claim they put it into service of the charity, or give you the value of what they got for it and almost universally these cars go straight to auctions and fetch not much (and many are bought by junkyards).
It does go to kids, it's just a religious charity for kids. That's an extremely normal thing. I'm Catholic, we have them too. And they're not hiding it.
I don't think it's a good donation! I wouldn't use it. Like I said, I'd junk the car and donate the proceeds.
> I don't really care about the religious aspect
I certainly do!
I'm a paying supporter of the Freedom From Religion Foundation, The Satanic Temple (it has nothing to do with satanism), and even the Friendly Atheist Podcast (which is just a podcast, unlike the first two). If I donated thinking I was helping families who couldn't get their kids to school or to after-school events and then found out that there was a religious org behind the commercials, I would be furious.
You can have and practice your religion. But bad actors have been using religion as an excuse for persecution and as a means of control in the USA for decades. I'm outraged to learn that they were manipulating people in this manner.
