Interesting. I've had ramps, but never found a good use for them. I think I got rid of them, not worth fishing out. But I do have a scrap piece of 2x10, and I'm due for an oil change in the next few weeks.This is true. There's enough clearance under the car to get the job done. Unless you're a really big person that is. I mentioned that I use ramps when I do this work, they're homemade ramps (made with scrap 2x10's) and have three steps. I only put the CX on the first step which is only 1.5" high. This is just enough to make that extra bit of room that makes is easier to maneuver under the car.
When I change oil in my MX I have to put the car on the top step.
Perhaps I'll just drive up on one thickness on the passenger front tire and see if its more comfortable that way.
