I can't answer your question. I purchased only one to use for my shed. The plywood ramp rotted and decided to try this ramp to get the riding lawn mower in and out. It works great for what I use it for.
If the ramp was wide enough to cover width of cars track it would weigh about 250 lbs and you would pay at least $250 for the one piece. Buy two of these and you spend around $100 and you won’t break your back moving them.
