If you were to use a similar system to what they use to hang bicycles with pulleys, set it up in a diamond formation so that each of 4 pulleys would be from a separate joist, that would average out to about 100lbs each. Shouldn't be a problem unless you're already structurally compromised. I'd unbolt as much as I could from it tho .. 500lbs sounds excessive
Wow…
I don’t think I have seen “Multiple MoPars” in any roof framing strength formulas.
We had a stripped VW body only (not the chassis) hung, from the rafters of a shop. We bolted chain to the rear bumper holes and around a couple 4x4s that were laid across the rafters to distribute the weight. It took about 4 of us (kinda like 5 with our Samoan buddy Manny) to lift it. It helped that it was going to be hung close to the back corner wall.
Good luck,

Get some chains, hooks & a forklift.......or lots & lots of friends.
I think if you can deviate from your plan you'd be better off with some industrial pallet racking to support it, but raising it will still be an issue. Build a platform/pallet the size you need & secure the car to it. The structure above a finished ceiling is usually designed to hold whatever the ceiling is only, like drywall.
