I tried to get in, it let me, and I backed it off of the other car and out. Anyway, I wasn't able to do that, but I WAS able to lift the back of one car so that it moved to the left and ended up at an angle, partially resting on top of the other car. If one car were on its side in the garage then I'd have more room. That's what I was trying to do after seeing it suggested by somebody else. The forklift isn't strong enough or big enough to actually lift up a car and carry it around, but it CAN kind of flip one. I drove it up to the garage, which opened its door even though there was no room for any more vehicles-not that I minded, since I needed to get at the cars that were in there. I drove the slow-ass thing all the way back to Dillimore, which didn't take as long as I thought it would, actually. You can see where forklifts can be found on the GTA wiki, but the one I got spawned next to the sawmill in Angel Pine. (I actually did download a mod to delete cars from garages among other things, but couldn't get it to start.) So if you see this post too late and run into this problem, here's how I solved it.

Thankfully I found a way to get around it without modding the game. So I googled it and found other people had experienced the same problem. And if you leave the garage and let the door close, then it will magically restore them to working cars again instead of making the wreckage disappear. I tried blowing them up too, but if you do that then the charred remains of the cars stay there taking up the same amount of space no matter how long you wait.

You can run against them and make them move some, but no matter how much you do it, they won't be moved far enough apart for you to get in one of them. Like they are right up against the walls and against each other. But I made the mistake of parking two cars in that garage and discovered only after saving my game (with the save before that having been a LOT of time before, so going back that far would lose me a good amount of progress) that if you do that there is NO room for CJ to walk into the garage and enter either car.
