Weighed my car today

Im really tempted to get some wheel scales, i have a bunch of cars i am curious about. It's just really hard to justify the the expense of even the cheapest set, just to satisfy curiosity.
I remember a few years ago a couple of guys would wheel weigh your car in the parking lot at the drags (no scale there) to help pay for their scales. I think they were getting $20 a pop. Im too old to try to pay for my scales that way, lol.
