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).
