those mustang ramps are way way over built, they are practicaly solid wood! so you have a 2,000 pound car, heaver in the front, right? lets say 1,200 pounds, 600lbs per wheel, sure that's a bit of weight, but not so much that solid wood is needed, I would say a 2x10 on flat with a suport every 24" inches should be more then enough, lets say you want to be really cheap (you know you want to) get a cinder block or two, and a 3 foot chunk of lumber without knots, and you have a ramp! curbs work too, old tires, a combination of those, and a floor jack.
