Oh absolutely. The only time ramps are not appropriate are when you have ground effects on the body that don't clear the ramps, or as the others are pointing out, you need to change a tire. On ours, ground effects are no problem. Straighten out the wheels, put the ramps down and kick them under the front of the tires. Put the car in 1st and motor on up the ramps. That usually gives you about 2 feet of clearance under the front of the car, plenty of room to slide under it and change the filter and oil.

Just do not go over the ramps and fall with the car down as I did. It hepls if you have somebody tell you how far to go and when to stop since you have to rev the engine to go up the ramp and stop once you are on top.

to keep from doing that, just keep one foot on the brake about half applied so the SECOND you let go of the throttle, the car stops. it is pretty easy to feel the bump on the end of the ramps if you know what you're doing. cinderblocks are not neccisary if on level ground because the tires sit in a little dipped in deal at the top and plus the car is in park so it cant roll anyways.

also. if you have ground effects and the ramps will not clear them, all you have to do is take a couple pieces of wood, lets say 2x4s preferribly 2x6s under each tire and then line them up along the slope of the ramp so the car just rolls right up on to the slope of the ramp without skipping any gaps. and with enough room, you can really clear the lowest ground effects if done correctly.

my ramps are definitely the best fluid changing accessory i know of, so much easier than jack and stands, MUCH safer and FASTER.
