I tear them down, drag them out to the closest maintained road, and cut them up with a sawzall, a process that was suggested to me by the county sheriff. I've found that the courts don't view trespassing or vandalism as very serious offenses even when you catch people in the act.
Bearrr264 used to roll vehicles that he found on his property on their roof.
I like the way you think.
The only reason that these scumbags would violate your land is that they must know that nothing much will happen to them. And, on many larger properties perhaps, the odds of being discovered are not very likely.
The idea of rolling vehicles is hilarious. They can't prove that the land owner did it and they now have the huge problem of getting the vehicle back on its wheels, which would require another vehicle to trespass on the land owner's property. Also, the vehicle may not run after it is upright again, requiring an expensive long distance tow job. Not to mention attempting to explain the cause of the damage to their insurance company, which might disallow their claim anyway.
