Ok so I have a pair of the rhino ramps and have used them for oil changes etc. I like them because they feel more stable to me(but I still have backup jack stands just in case). Couple things I learned. I'm at stock hieght. It would have been really iffy for me to drive onto the ramps....I may have made it or I might have scraped the bumper, you'll want something to raise you a little before you go onto the ramps, or jack the car up onto the ramps. The worked well for me and give me pretty good hieght. I can fit under the car fine(6'2", 200).

It seems to me that ramps are getting harder to find. I used to use them all the time because they were easy but it was a pain to find them this time....

 

Kragen has Rhino ramps for $20.
