Friend of mine in Ohio had a Jiffy Lube back in the late 90s. There were holes cut in the floor and the floor was supported by steel beams. Underneath there was a movable steel platform that was hydraulic and could be adjusted for height. They would pull the car or light truck over the hole which had guide rails so a wheel wouldn't fall in, one guy would work underneath dropping the oil in a catch system and change the filter, then check manual trans and rear end fluid, while the guy/gal would fill the oil, check auto trans etc. They could do a vehicle in very little time. Everything was spotless.
