I just finished my first under car oil change. I decided with the number of items to be checked underneath the car, it was time to get some ramps to make it safe. Advanced Auto Parts had the Rhino 12,000 pd safe set (plastic) for $49 (not on sale) but time is money and I needed them today. I just finished my oil change and it went so well. The ramps were the right size and height, 12 in. wide and just under 7 in. tall. Worked great. Just thought I would share that.
