Stingray I have used my 2 post on C1's and My Model A. Just like Big said you can do more and easier than with a 4 post.
2 posts take up less room (you don't have 4 posts and you don't need the extra length for the ramps), you do have to drill into the concrete (need about 4 inches), you can store cars on them, and you do not have to purchase a rolling jack to work on brakes or front end.
