When I read an earlier post sying he uses cement blocks, I was going to post the same. It is a BIG no no.I would never ever use concrete blocks to support a car.
If a cement (actually, it's concrete. Cement is only an ingredient of concrete) is given a shock or overloaded os it cracks, its strength goes from 100% to 0% in a micro second where as wood will mostly retain its strength. There is less chances of wood (unless it is oily) slipping too.
For your own sake (and your family), DON'T DO IT!
